Even Europe thinks Obama is weak on Iran:

European officials are increasingly concerned that Sen. Barack Obama's campaign pledge to begin direct talks with Iran on its nuclear program without preconditions could potentially rupture U.S. relations with key European allies early in a potential Obama administration.

The U.N. Security Council has passed four resolutions demanding that Iran stop enriching uranium, each time highlighting the offer of financial and diplomatic incentives from a European-led coalition if Tehran suspends enrichment, a route to producing fuel for nuclear weapons. But Obama, the presumptive Democratic presidential nominee, has said he would make such suspension a topic for discussion with Iran, rather than a precondition for any negotiations to take place.

European officials, speaking on the condition of anonymity, said they are wary of giving up a demand that has been so enshrined in U.N. resolutions, particularly without any corresponding concessions by Iran. ... "Dropping a unanimous Security Council condition would simply be interpreted by Iran and America's allies as unconditional surrender, and America's friends would view this as confirmation of America's basic unreliability," said François Heisbourg, a Paris-based military analyst with the International Institute for Strategic Studies. "A hell of a way to start a presidential term."
