WYour name says it all, an evil family with a horrible history.
Abu sufyan who was one if main leaders of bani omaya fought prophet Mohammed. His wife hind killed hamza and ate his liver. Muauwaya son of Abu sufyan faught against Ali Ibn abi talib, than against Hassan Ibn Ali. Yazid Ibn muawaya killed the prophets grandson and his whole family, and took the women of the prophets family captives. Wow what a great history. You must be really proud.
Allow me to say screw you and Banu omaya. Why haven't you chosen bani Hashim instead, or your hate for the prophets family doesn't allow you. Iraqi Kurdistan may be ejected because it has no use for iraq, it is just a cash drainage, but iraq won't split, that's just a dream that you would like to happen. Iraq is growing stronger and by 2020 we will put the gulf states in their real place, it is iraq who has the say in the region, just because iraq is weak right now it doesn't mean it wit rise again.
Anbars Sunni tribes are the ones go made the sahwa and faught against Sunni extremists. Besides all the oil resources are in Shia south, so unless they want to split from a thriving economy, join syria instead which barely has money to sustain its own citizens, they won't do it. The Iraqi army controls all the towns and cities in anbar.
Iraq didn't die not even during the worst of its states in history (2004-2007). It's not going to now, especially since there is a stronger army, Better economy.
You Saudis couldn't even deal with the houthis although they are just a sma banned of fighters, So you Shouldn't be talking. Anyways all the Shia south is safe, so any conflict will mostly affect the Sunnis.
