ISIS was not formed in Afghanistan nor in Iraq, it was formed in Syria.
Syria is going through a serious civil war, and the USA doesn't quite like the current syrian dictator, so they armed the rebels with guns and such.
Though, the rebels decided it was no longer good to waste effort fighting the government. They dropped the bloodshed against the government temporarily and formed a "caliphate" that has never been recognized as a nation in Kurdistan's region. And there they stood, recruiting, gaining power slowly.
The Iraq/Afghanistan wars has not much to do regarding the foundation of the ISIS. Specially because Afghanistan is not linked nor borders their territory. As for Iraq, likely some iraqi people who hated the USA for the attack joined the ISIS, that could be true, but their founders are not iraqi, so it's not directly the USA's fault.
As for the islamic radicalism in Afghanistan... I'd say these tribemen are ungrateful fools, america saved them from the USSR in the past, and using the guns they gained in the process they later attacked the western world because of different visions of morals.
Iraq is just the tip of the iceberg. Beneath the surface are the disasters brewing in Afghanistan, Libya, Pakistan and Sub-Saharan Africa. Add to that the possibility of the Syrian-ization of Ukraine. These are the fruits of US destabilization.
As mentioned before, Pakistan is a big deal. Ever played World Countries 2012/2014 map? There is a reason Pakistan is 5 in 2012 and 7 in 2014. It has nukes and a powerful military power.
How so? The Taliban formed in response to Soviet invasion. America's mistake in the matter was supplying and supporting the Taliban, but there was no way of predicting what the Taliban would turn into after the Soviet invasion ended.
Just one thing, though: It wasn't the Taleban, the original group formed was Mujahideen. It later split into Taleban (national terrorism - took over Afghanistan) and Al Qaeda (international terrorism - 9/11'd the WTC)
- Kurdish autonomy
-annihilation of Taliban, Hussein, Bin Laden
Kurdistan is not an official country yet, and I can't see how that is bad. Hussein and all other Iraqi/Syrian leaders hunted them to death. And nowadays they are being genocided by ISIS. Also, I fail to see how the deaths of Saddam Hussein, Osama Bin Laden and the extermination of the Taleban are bad things.
