Middle East

As someone who doesn't know allot about how the middle east works a few questions come up about the recent revolutions that bother me.

1) Is it possible that 9/11 could have been avoided if the U.S. took a more firm stance againts regimes in the middle east that showed little respect for democracy or human rights? (in other words not support them?)

2) Would it be practical in a strategic or economic sense for us to not do buisness with these kind of states? If so why aren't we?

3) What can the U.S. do to improve its own human rights record after some of the things its done during the war on terror? (for example detaining people for years on end without charges or trial and torture)

I wish you'd be more specific as to what liberty's your refering too that liberals apparently beleive in.

i'm just wondering how much of the anti-americanism in that part of the world comes from who are freinds are, and do we have options to change that? I mean for christs sake we demanded amnesty in the un for the mercenaries who slaughtered peaceful protestors in libya to proctect our contractors for what they've done in iraq. how could they not hate us after that? How could that not empower al qaeda?
