What does the International Community expect Iran to do?
Iran is really in a catch-22 situation:
1) It (potentially) builds nuclear weapons. The UN levies sanctions, US eventually invades with an "international coalition".
2) It ceases everything. The US eventually invades.
What would you do if you were Iran given that:
1) The US lumped Iran along with Iraq and NK in the Axis of Evil speech. Iraq was invaded and didn't have nuclear weapons. America will clearly never invade NK despite having a strong presence on her doorstep because she has nuclear weapons.
2) Despite Syria hopping on one leg, rolling on the floor, begging at the US's command, the US is still extremely hostile towards the country. And will probably invade or use Israel as proxy.
