Is Obama's 'let's talk' diplomacy failing?

The answer is yes and very few on the right are surprised.

President Obama may be willing to talk to America's adversaries abroad, but six months into his tenure hardly anyone is returning his call – a situation that is prompting restiveness in Congress and a round of "we told you so's" by diplomatic hawks.

In one sign of impatience with Mr. Obama's approach, the US Senate in late July unanimously urged the president to seek "crippling economic sanctions" on Iran if it does not move soon to abandon its nuclear ambitions.

Whether the issue is key security threats, as with Iran and North Korea, or lower-profile matters, as with Cuba or Burma (Myanmar), Obama's critics and even some backers of the "talk to the enemy" approach are starting to speak of the policy's limits.
