The question for the historians:
Would ISIS exist if Saddam Hussein was still in power? Did Bush facilitate or delay the emergence of ISIS?
That is the question(s).
Would ISIS exist if Barack Obama hadn't released it's commander in 2009? Would ISIS exist if Barack Obama had agreed to a reasonable level of troops agreement with the Iraq government instead of petulantly refusing to and removing our forces (surrendering Iraq)? Did Obama facilitate or delay the emergence of ISIS?
That is the question(s).
