One thing that really annoys me are politicians (most often American ones) saying that we should stop "interfering" in the world and deal with our own problems.
That's rather a selfish view, IMHO. Plus, these problems don't get better without outside intervention. Two, if we were to, par exemple, withdraw from Iraq prematurely, there would be a failed state that would cause problems for America, Britain and other countries.
Where are the internationalists in American politics? And don't say the protectionist Democrats are better.
