The latest NIE, about which I have already blogged, is much the rage in the media and among the Democrats. The thing is, even the increasingly dhimmi Brits aren't buying it: http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2007/12/09/wiran109.xml. The way they see it, this NIE will embolden the Iranians (gee, ya think?), may very well be wrong (given the failures of U.S. intelligence in the Middle East, not a stretch of the imagination by any means), and will likely spur the Israelis to attack Iran on their own (which would be universally condemnded worldwide, just as the 1981 attack on Osirak was, until, years later, people acknowedge that it was the right thing to do).
The Brits are likely right on this one. We trust the Iranians at our own peril.
