I discussed the present situation. History is interesting, I agree, but to only start laying blame for events happening generations ago isn't a counterargument, it is lack of arguments.
(And I did answer meric's "argument" that everything happening is USA's fault by pointing out why the situation is different now. No one seems to have a counter argument?)
And for changing things in Iran et al, check the resource curse on Wikipedia. Countries that weren't democracies when they found oil didn't become democracies. (Norway already was democratic before the oil.) It is just too lucrative for the leaders to oppress the population and steal the money.
