I read a recent editorial by Daniel Pipes, who fronts the Middle East Forum and other information outlets on the web. He's an academic who has built a career out of studying the ME.
In short, he said that in order to properly put the Iranian bent on nuclear weaponry right out there in front where it belongs, it's best to leave I'm-a-nut-job right where he's at.
Ali Khamenei, the REAL power-holder in Iran, is far less in-your-face than I'm-a-nut-job. And make no mistake - he's pushing the nuclear weaponry agenda with a lot more ooomph than I'm-a-nut-job.
It's best to keep the lunatic out there braying his lunacy, rather than bring the new guy on board, because they're both singing off the same sheet of music.
The West can be teh Stoopid at times - forgetting completely about the danger because it's been cloaked in reason and soft words and "accommodations" which are anything but.
