The people we trust to intervene have their own set of agendas. If Iraq isn't a prime example of this I don't know what will serve as one. Thus most actions taken to intervene abroad will bring negative repercussions our way at some point in the future.I think our inactions are more responsable than our actions.
We should have taken care of afganistan better after the soviets left.
We should have gone after al queda sooner.
We should have somehow made the CIA better.
We should have taken bin laden when he was offered to us.
As much as I hate to think of what the U.N. will grow into I can't deny that for the time being they make honest efforts to intervene for peace, they don't overstay their welcome and they don't make deals with strings attached.
