Bush really did mess up in the middle east but Bush's fuck up in the middle east should not be compared to Obama's. Obama did what he had to do and at the end of his presidency the situation int he middle east was way better than it was when he entered.
A war with Iran wont happen. Trump has been pulling troops out of the middle east but unfortunately he is also increased military spending.
Look at Lybia, today is much, much worse than before Obama bombed it to nothing and killed Gadaffi. No country US invaded since its "war on terror" began is better than it was before.
God bless Putin in Syria, if it wan't Russia defending the secular regime of Assad, it would have been replaced by a barbaric islamic caliphate by the US.
Gadaffi didn't get killed by Obama, but by a mob of Lybians who finally saw a chance to get rid of him.
As for Syria, not so sure. The US (among others) were supporting the more secular and moderate rebels to fight both Assad and ISIL. And that worked pretty well until the Russians started bombing them instead of ISIL.
Also, while ISIL would have been absolutely barbaric, Assad ain't that much better. He's a secular barbarian compared to ISILs fundamentistic barbarism. Why do you think so many people in Syria were and are willing to fight against Assad? Certainly not because he's a good guy! ISIL is defeated, but the fighting is still going strong because Assad just ain't much better than ISIL would have been.
While we're at it, you criticise Obama for outbombing Bush in the middle east. You know who outbombs Obama several times over? Putin!
But again, comparing Bush to Obama here is very misplaced. Without Bush critically destabilizing the whole region by invading Irak, it wouldn't have come to this in the first place.
