He knew. That's exactly why he did it. Someone had to, it was the only way to send the message that this isn't Obama, you don't get to align yourself with Hezbollah and kill Americans with impunity whenever one feels like it then hope a plane and go home. This sort of total disregard would have came to a head eventually, better now then later down on the road as you know showing this kind of disrespect is pretty clear cut that behind closed doors they aren't abiding by any "peace" accord.

ps. you can't give twenty five million to one candidate, it's against FEC regulations, he may have reached that amount by giving to various pacs or multiple candidates in those pacs.
