I am just going to go ahead and call out all the usual Reich-wing Republican suspects who do not support Ron Paul for president as the real Isolationists -- on the following grounds:
1) You want to build bigger fences to keep people out.
2) You do not want trade with the entire world (and simultaneously confuse the government's of other nations for the people they oppress).
3) You believe the US should have the world's only military super-power and will stop at nothing to keep other nations from defending themselves against its might.
Let the excuses begin.
