Iran given ONE week to enter nuclear talks, or
1. The EU will write a STRONGLY WORDED LETTER OF CONDEMNATION
2. The US will offer GENEROUS INCENTIVES
I think what's really needed is 'if you don't play ball Mr Mullah, we'll capture you and hand you over to the families of people you tortured to death. Or, maybe we'll just put you in a cell with a couple of bull queers for a week before we shoot you'.
Allowing Iran to have nukes is like giving a box of matches and a bunny rabbit to a child who likes to start fires and torture animals.
