Part of the reason why it's aggravating trying to convince people about defense, is that Paul doesn't do it himself most of the time. He always says what we shouldn't be doing, but he doesn't talk much about what we SHOULD be doing instead.
He's supported the SDI, submarine technology, and the hypersonic weapons that reach anywhere within an hour. He doesn't talk much about this though and that's why people think he's weak.
YOU NAILED IT!!!!!! I love the guy but he does come off as weak, even I have my doubts sometimes if he does really grasp foreign policy. I know he does, but as you say it'd be nice if he said it once in awhile.
