Assalamu Alaykum,
Of course no Muslim should be fighting another Muslim or even non-Muslim. Such violence is against Islam.
Obviously, if they break peace and we have to defend ourselves.
There
are many major differences between Sunni and Shia. To the extent that the Group Shia are not deemed Muslims, and this is by consensus of the majority of Scholars. However, we can not say that any one individual is a non-Muslim.
The Shia are derived from Abdullah bin Sabah who was a Jew heretic who despised Muslims. This is mentioned in many of the Shiite's old books written by their own scholars, but, nowadays they try and hide this fact and pretend it is not true, they do the same for most of their beliefs.
Shia do not believe in the same kalimah as the Sunni (they normally add something like (Ali wali'Allah)), nor do they have the same beliefs. They have different Aqeedah (belief in Allah) - They associate partners with Allah by believing in various "infallible" Imams, some such as the alavi shia go to the extent of saying that Ali(RA) was God.
They Curse the Sahaba (which is part of their pillars) - They say very bad things about the Companions of the Prophet
, they curse Aisha and they say she and Abu Bakr, Umar, Uthman, Abu Sufyan (the Prophets Uncle), Abu Hurayrah and many of the Sahaba are "kafr" or non-Muslim. Its part of their beliefs (they have their own pillars) that they have to curse the Sahaba. It is in their books and main beliefs that whoever does
not curse them, then he is an enemy of theirs and is not a Muslim. - So this means that Sunni are their enemies because we do not say the disgusting things they do.
and they do various twisted innovations such as Taqiyyah (lying to cover up their beliefs) and Mutah (temporary marriage, which is haram).
Due to Taqiyyah, they deny everything, they will even deny their own fundamental beliefs such as their cursing of Sahaba.
They do fool many Muslims by their propoganda and are not to be trusted.

Any sort of violence such as that shown in Iraq is unIslamic and haram. It is murder. Allah knows best the perpetrators of such acts.
As for sects, then this is something that is apparent and is an unfortunate circumstance of our Ummah. To deny the existance of sects is lunacy and ignorance. The Prophet
himself said that the Ummah will be split into sects and that all of them will be in the hellfire except one>
"And this Ummah will divide into seventy-three sects all of which except one will go to Hell and they (i.e. the Saved Sect) are those who are upon what I and My Companions are upon (i.e. those who follow My Way and the Way of my Companions.)"
[Reported by at-Tirmidhee - Hasan]
The Following is from IslamQA,:
It is the Muslim’s duty to follow the truth and to join the victorious group, the people of Sunnah and Jamaa’ah (Ahl al-Sunnah wa’l-Jamaa’ah) who are followers of the pious predecessors (al-salaf al-saalih), loving them for the sake of Allaah whether they are in his own country or elsewhere, and cooperating with them in righteousness.
The attributes of the victorious group are related in a number of saheeh ahaadeeth, for example:
The Prophet
(peace be upon him) said: “My ummah is an ummah which carries out the commands of Allaah; those who let them down or differ from them do not harm them and they will keep adhering to this path until the Day of Judgement.”
Mu‘aawiyah and ‘Umar ibn al-Khattaab (may Allaah be pleased with them) reported that the Prophet
(peace be upon him) said: ‘A group of my ummah will continue victoriously adhering to the truth until the Last Hour begins.’”
Al-Mugheerah ibn Shu‘bah (may Allaah be pleased with him) said: “I heard the Messenger of Allaah
(peace be upon him) say: “Some people of my ummah will remain victorious over the people until the decree of Allaah reaches them.”
‘Imraan ibn Husayn (may Allaah be pleased with him) said that the Prophet
(peace be upon him) said: “A group of my ummah will continue fighting for the truth, and will prevail over those who oppose them, until the last of them will kill al-Maseekh al-Dajjaal (the Liar or Anti-Christ).”
From these ahaadeeth we may understand the following:
(1) The Prophet’s words “A group of my ummah will continue . . .” indicate that this is a section of the ummah, not the entire ummah. This also indicates that there will be other groups and sects.
(2) His words “those who oppose them will not harm them” indicate that there will be other groups who oppose the victorious group in the way they practice the religion. This also concurs with the hadeeth which describes the ummah being divided into seventy-two groups or sects who oppose the one group that is following the truth.
(3) Both ahaadeeth offer glad tidings to the people who are following the truth. The hadeeth that speaks of the victorious group speaks of their victory in this world.
(4) The words “until the decree of Allaah reaches them” refer to the wind or breeze that will come and take the soul of every believing man and woman. This does not contradict the hadeeth “A group of my ummah will remain victoriously supporting the truth until the Day of Resurrection,” because that hadeeth means that they will continue to follow the truth until that gentle breeze takes their souls just before the Day of Resurrection, when many other Signs of the Last Hour have already manifested themselves.
The characteristics of the victorious group
From the ahaadeeth quoted above, and other reports, we can derive the following characteristics of the victorious group:
(1) They follow the truth. They are described variously as “following the truth,” “following the commandments of Allaah,” “following the true religion,” etc.
All of these phrases indicate that they are adhering to the true religion with which Muhammad
(peace be upon him) was sent.
(2) They obey the commandments of Allaah, which means:
(a) They are distinguished from the rest of mankind by carrying the banner of Da’wah towards Allaah.
(b) They undertake the mission of enjoining what is good and forbidding what is evil.
(3) They will be victorious until the Last Hour.
The ahaadeeth say that “they will be victorious until the decree of Allaah comes,” “they victoriously support the truth,” or “they will be victorious over those who oppose them.”
This victory includes:
Being open and not hiding: they are well-known and prominent and have the upper hand.
Adherence to true religion, righteousness, following Allaah’s commands and fighting against His enemies in jihaad
Victory by defeating others
(4) They are patient and resist others with patience.
Abu Tha‘labah al-Khashani (may Allaah be pleased with him) reported that the Prophet
(peace be upon him) said: “After you there will come days of patience, in which the patience required will be like having to hold a burning coal in one’s hand.”
Who are the people of the victorious sect?
Al-Bukhaari said: “They are the people of knowledge (the scholars).”
Many scholars said that the victorious group is the scholars of hadeeth.
Al-Nawawi said: “It is possible that this group is scattered among all types of believers. Some may be brave fighters, or fuqahaa’, or scholars of hadeeth, or ascetics, or people who enjoin good and forbid evil, and other types of good people.”
Al-Nawawi also said: “It could be a group of different types of believers, including those who are brave and skilled in warfare, faqeehs, scholars of hadeeth, Qur’aanic commentators (mufassireen), those who enjoin good and forbid evil, ascetics and devoted worshippers.”
Ibn Hajar, may Allaah have mercy on him, explained the matter as follows: “They do not have to all be in one city; they could be gathered in one country or dispersed across the world. They may be gathered in one city or in a part of it. It is possible that one group may exist, then disappear, then be replaced by another group, and so on, until the Day of Judgement, when all will disappear except for one group in one city, who will disappear when the breeze decreed by Allaah comes.”
The scholars’ discussion of this group does not specify one type of people, or one city or country, except for the last group, which will be in al-Shaam (the territory comprising modern-day Syria, Lebanon, Jordan and Palestine) and will fight the Dajjaal, as the Prophet
(peace be upon him) said.
No doubt those who are involved with the sciences of sharee’ah – ‘aqeedah, fiqh, hadeeth and tafseer, studying and teaching – are the people who are most qualified to be called the Victorious Group, and they should be at the forefront of da’wah and jihaad, and enjoining what is good and forbidding what is evil, and refuting the people of bid’ah, all of which must be accompanied with sound knowledge based on the Wahy (Revelation).
-------------------------------------------------------
Shaikh Salih al-Fawzaan was asked, "Is Salafiyyah a hizb (party) from amongst the parties. And is ascribing to them (i.e. the Salafis) a blameworthy thing?"
To which he replied, "As-Salafiyyah (i.e. the Salafis) is the Saved Sect, and they are Ahl us-Sunnah wal-Jamaa’ah. It is not a hizb (party) from amongst the various parties, those which are called "parties" today. Rather they are the Jamaa’ah, the Jamaa’ah upon the Sunnah and upon the Deen (religion). They are Ahl us-Sunnah wal-Jamaa’ah. The Messenger (sallallaahu alaihi wasallam) said, "There will not cease to be a group from my Ummah manifest and upon the truth not being harmed by those who forsake them neither by those who oppose them" and he (sallallaahu alaihi wasallam) also said, "And this Ummah will split into seventy-three sects, all of them in the Hellfire but one". They said, which one is this O Messenger of Allaah? He replied, "They are those who are upon what I and my companions are upon today". Hence Salafiyyah is a group of people (i.e. the Salafis) upon the madhhab of the Salaf, upon what the Messenger (sallallaahu alaihi wasallam) and his companions were upon and it is not a hizb from amongst the contemporary groups present today. Rather it is the very old Jamaa’ah, from the time of the Messenger (sallallaahu alaihi wasallam) which inherits (this way) and continues, and which never ceases to be upon the manifest truth until the establishment of the Hour, as he (sallallaahu alaihi wasallam) has informed (us)." (Cassette: "at-Tahdheer min al-Bid’ah" second cassette, delivered as a lecture in Hawtah Sadeer, 1416H).
---------------------
We call ourselves Muslims and we encourage cooperation and love in our Ummah, at same time we can further describe ourselves as Sunni or Salafi. These simply are descriptions. Meaning, that we follow the Quran, Sunnah and way of the pious predecessors. - This is in accordance with the verses from the Quran and the Sahih Hadith and is a view shared by the Companions of the Prophet, the first few generations of Muslims and the greatest scholars of Islam.
Because, at the time of the Prophet
it was evident that they were all Muslims and if they differed in anything, they would go back to the Prophet
Islam is always protected, and as the hadith above showed, there is always one group of people that is upon the Truth. Of course, No Muslim says they are perfect, so may Allah make us amongst those who are rightly guided.
