Ron Paul is dead wrong, and is hoodwinking a lot of gullible people about a declaration of war. There are some very excellant and compelling legal reasons why a declaration of war is not supposed to be used by any other than a few nations since the Second World War. Until you can enumerate those reasons and understand them well enough to debate the reasons for their existence, you are arguing from blind ignorance. The question then is whether or not Ron Paul is arguing from blind ignorance, or he knows what he is doing is wrong and deceptive?
Considering he didn’t have a problem with a non-declaration of war with the authorization to use force in Afghanistan shows he is being deceptive. He was just joining the chorus that wanted to call Bush a war criminal.
