All of that list can be laid to the feet of Obama and Hillary.
None of those are the result of what Bush did, but of what Obama did afterward, in particular Libya was Hillary’s War.
Had Obama continued Bush’s policies and deployments with the same ROEs, then Iraq would likely be stable and not under Iranian control. Gaddafi would still be around as would Mubarak.
Syria has always been within Russia’s sphere of influence if for no other reason than Antioch where Russian Orthodox began.
Trump is absolutely wrong. Both of you are buying into the liberal meme.
If Bush leaves Saddam alone, the rest of chain reaction never takes place. Obama was never going to invade Iraq. Absolutely and unequivocally Iraq invasion by Bush-43 was the worst foreign policy blunder since Vietnam blunder.
I will grant you that Obama/Hillary speeded up the kerfuffle in middle-east. But it was inevitable. American troops could not stay in Iraq for ever. Islamic extremists will never suddenly turn peaceful. Allah will not permit that.
The invaluable lesson: Leave non-jihadists dictators alone. They can control the jihadists much better than American military ever can. If you have missed this lesson, I am afraid you do not understand Muslims, Koran, Islam, jihadists and the middle-east.
