"A bit of air support" is a strange characterization for destroying the Libyan government's entire tank fleet in the middle of an Islamist uprising. "Mainly keeping out of it" is a strange characterization for supporting a coup in Egypt that toppled a democratically elected government. Also, we never, ever, ever, ever talk about Bahrain, where the US supplied arms through Saudi Arabia against the uprisings and: >By 2014, 5,000 Saudi and Emirati forces and almost 7000 American forces were positioned "less than 10 miles from the Pearl Roundabout, the center of the country’s protest movement."
We have surrounded the middle east with armies for more than a generation and armed the worst governments in the area. "Mainly keeping out of it" is a gross mischaracterization of what we do there.
I don't recall any major role for the US in the Tahrir Square uprising in Egypt except just saving their interests whether in the Presidency or the military but saying that the West orchestrated the whole thing is just blatantly false and totally dismisses the sweat and blood we Egyptians scarified to get rid of dictatorship and take all the credit for themselves.
Now to ISIS, we could argue that ISIS was a byproduct of the Iraq invasion in 2003. ISIS was born out of the Iraqi Insurgency and the Al-Qaeda in Mesopotamia under the leadership of Abu Mosab Azzarqawi.
So yeah the US invasion of Iraq contributed indirectly to the rise of ISIS in Iraq first and then to expand in the neighboring Syria and eclipsing Al-Qaeda as the "hottest" Islamic terrorist organization in the world.
For goodness sake, we'd been trying to topple Gaddafi and the Syrian regime for half a century and getting exactly nowhere, then as you say one Tunisian street vendor makes a desperate gesture and in the chain reaction from that the whole region falls into chaos. That's history for you.
As for IS, the reason they're such a nuisance isn't so much due to the invasion of Iraq, it's due to the power vacuum in north western Iraq caused by the withdrawal of US forces in 2011. The fact is the surge worked, but all of that was willingly thrown away.
