Answer 1
they all have problem of only presence of US in Iraq.
Answer 2
There are far more substantial problems between the Shiite Arabs, Sunni Arabs, and Kurds than just the American Armed Forces which have departed Iraq since December 16, 2011. It is also unhelpful to see the conflict as a religious conflict. In Iraq, people traditionally organize politically by their religious group.
As a result, there have been numerous confrontations between Iraq's diverse population for political advantages. Among these conflicts exists a conflict between Sunni Arabs and Shiite Arab, especially near Baghdad where the neighborhoods are evenly mixed between them. As a result, we also have seen numerous Shiite-Shiite conflicts in areas where rival Shiite leaders were competing for power. The Iraqi Army and Police Force and tried to maintain a lid on the various factional groups, such as the Sadrists, Shi'a Groups in the Shi'a Holy Region, Sunni Arab Fedayyin, the Kurdish Pershmerga and branches of the PKK from attacking each other and establishing power bases.
Kurds and Sunni Arabs want increased autonomy from the central government. Kurds want their own rule in order to practice their own culture and defend themselves from violent attacks and genocides. Sunni Arabs (especially in Anbar Province) want autonomy in order to retain the local control that that they had under Saddam. Shiites, as the majority, prefer a more powerful federal system.
the Sunnis are the majority and the shiites are the minority.therefore the numbers of Sunnis are more than shiites populations.
No, Shiites outnumber Sunnis in Iraq. However, Sunnis over the world outnumber Shiites. World statistics is that Sunnis Muslim world percentage is 85% of total world Muslims. While Shiites are less than 15%. Refer to question below for more information.
No They are not Sunnis. They are Shiites.
There is no war between them Only the extremists create problem
What caused the split was Muhammad's death in 632.
The Sunnis are of bigger population. Of world Muslims, 85% are Sunnis.
Some Sunnis hate some Shiites and some Shiites hate some Sunnis, but the majority of the conflicts between them are not theological, but political, social, and economic. These labels work similarly to ethnic labels in the Balkans, ripping people and countries apart. It does not help that many Sunnis and Shiites purposely or unintentionally misconstrue the doctrines of the other in order to give Divine Legitimacy to what would otherwise be a vulgar brawl for resources.

Answer 1Yes. However, there was no real split between Shiites and Sunnis. It is just some different views over some side issues that are not critical.Answer 2No. The split between Sunnis and Shiites occurred nearly 30 years earlier when Abu Bakr was elected by the Shoura Council to the position of Caliph against the will of Ali's supporters. Those supporters rejected the decision of the Shoura Council and became the Shiites. The Battle of Karbala crystallized this division since Ali had, by then, been assassinated, and his son Hussein (who was the next candidate supported by the Shiites) was butchered by the Caliph Yazid I without Sunnis rejecting Yazid's right to the Caliphate.
