There are no easy answers to these questions.

On the one hand you don't want Iran to build nukes for obvious reasons, but Iraq did send a message that the US will only attack countries who can't defend themselves. Ex. North Korea If history has taught us anything, putting your head in the sand can lead to dangerous consequences. Tough choice.

Iraq was a mistake and you can never justify the loss of soldiers lives there. On the other side Al Queda has been weakened while fighting there and again there hasn't been an attack on American soil since 9/11. Coincidence or not?

Russia- Georgia has been a huge ally to us, so you can't just sit back and do nothing. On the other hand, they aren't completely innocent either.

I don't see things as black and white/right or wrong. It is just a matter of seeing both sides.

In the end, McCain isn't Bush, just like Obama isn't Clinton. Same party but different people with hopefully a different way of doing things.
