Although it appears to me that Huffington Post is deteriorating in its coverage of real issues, I think that this is a very well reasoned and fact-based analysis of the current US - Iranian stalemate.
...Obama's administration has made an ill-considered wager that it can "diplomatically" coerce Iran's abandonment of indigenous nuclear fuel cycle capabilities. This is dangerous. ... it will eventually be left with no fallback from which to resist pressure from Israel and its friends in Washington for military strikes at least against Iranian nuclear facilities.
