Insight Dr. Paul's position on the Afghan war, how he, if President and in the US Congress, would capture Bin Laden, and routine counter terrorism efforts are better understood with this post from his blog:
They outline how Ron Paul submitted a Letter of Marque and Reprisal in 2001. That is a way for a nation to "get back" at a state or non-state offender in a way that is proportional to the offense, thereby reducing the chances for total war.
Wow, imagine that, a measured and direct response, instead of attacking the wrong country with our whole army. That Ron sure is NOT kooky!
