The US has dropped its objections to Iran beginning talks to join the WTO. On the face of it, this agreement looks like another instance where EU negotiators undermine and wear down the US. But this now looks more like a shrewd move on the part of US officials. The final approval for talks came after an Iranian pledge (which is not worth the papyrus it's imagined to be written on) to continue a moratorium on uranium enrichment.
So the US gives up something it really didn't need to get Iran to further pin itself down under its own dishonesty. Accession to the WTO can take at least five years (so far it's taken Russia ten) and requires that the country requesting membership engage in bilateral negotiation with any member nation that requests it. This would give the US another opportunity to frustrate Iranian ambitions while keeping closer tabs of what's up with the Mullahs.
This will take some deft handling, but the US can use this latest development to further undermine the Mullahs while demonstrating a more pragmatic side in dealing with Middle East dictatorships.
