When the vice president is a loose cannon, you never know if what he says is a gaffe or a major policy change.
"Israeli officials have welcomed comments by US Vice-President Joe Biden that America would not stand in the way of an Israeli strike against Iranian nuclear plants. Mr Biden contradicted his country's most senior military commander, Admiral Mike Mullen, when he responded, three times, to questions on the American ABC's This Week program that Israel was free to do what it needed to do. "If the Netanyahu Government decides to take a course of action different than the one being pursued now, that is their sovereign right to do that. That is not our choice," Mr Biden said. Israeli officials have read the comments as a sign the US is preparing a "plan B" in the event that its proposed dialogue with Iran fails to rein in Tehran's uranium enrichment program."
Either the Obama administration just shifted gears on Iran (i.e., the U.S. no longer opposes an Israeli preemptive attack on Iran), or Biden should be told to shut up.
