No. But to pretend that there are not negative consequences from withdrawing from foreign alliances and activity is either naive or stupid. I think one of the major causes of our current economic downturn is rising energy costs. Should we cease to have a role in Middle East policy, we could easily see results which would change the entire way we live. Isolationsism could impact our lives for the worse far more than this supposed "Empire building" has.
And I think it is oversimplification to the extreme to say that this happened solely because of our role in the Middle East (i.e. - we're friends with Israel). Radical Muslims hate capitalism. They hate democracy. They hate people who aren't radical Muslims. And a withdrawal will not be seen as "for our good." But rather as cowardice. That won't bother you. But when terrorists smell cowardice, that's blood in the water.
When a country is as strong as we are, and we impose our will on countries unable to resist us, we are engendering hatred. If we are afraid to sustain our power, by keeping peoples under our thumb, we will sustain many such attacks as happened last Tuesday. There is only one way to stop these attacks, that is to conquer lands, and occupy them. Are you, and by extension we, prepared to do this?
