Palin on Foreign Policy

Given America's present position of influence in the world, I sometimes wonder whether US foreign policy* has a more significant cumulative effect on humanity than all their domestic policies put together.

It is also why hearing Sarah Palin speak on the matter leaves me cold.
*And environmental policy, at least the aspects that respect no national boundaries.
