The agreement between Iran and western governments, on Iran freezing its nuclear programme, in return for some relief from economic sanctions, is a good thing.
The Geneva deal eases political tensions and reduces the possibility of military action against Iran. Political friction may still ratchet up if either side fails to deliver, if further investigation of Iranian nuclear capability shows military development, or if Israel kicks up enough fuss to undermine the agreement.
Lifting sanctions means the Iranian state and bourgeoisie will be able to claw back billions of dollars from frozen bank accounts.
But sanction conditions have been used to attack Iranian workers, to suppress working-class leaders, and these attacks will not be lifted.
