With all due respect, Reagan negotiated from a position of strength. The ABM system and deployment of the Pershings to Europe was called saber rattling at the time interestingly enough. I think some find the use of strength to be frightening at some level, whereas others are hopelessly wrapped up with moral equivalence coupled with liberal guilt. Not saying that describes you but it certainly does a number of recent posters on this thread imho.

Back to topic, Obama's upbringing was fundamentally anti-Western and we're seeing the fruits of that now. He is by no means negotiating from strength because it's obvious that iran does not fear him ... why should they?
