The Iranians would be smart to hold out

for a "one and done" agreement. The West, the US and Israel mainly in the last many decades, has a history of making agreements that are "stages" with various parts dependent on other parts. These always fall apart down the road and the "if, then, when" aspects are all fodder for more argument and attack.

This is part of what the Arab countries were apprehensive about in the UN partition plan for Palestine to begin with. Always the West makes promises about "down the road" they'll do things etc. So it was for right of return and compensation for Palestinians. So it has been for Gaza and the West Bank. So it has been for Lebanon and Syria. Now it is Iran that is being asked to go for this kind of "phased" deal. They would be wise to say "na, mersi" or any of the other Persian forms of saying no. A global agreement on all issues or nothing is the wisest move because otherwise this is guaranteed to be like all of the other so-called "agreements" where the spying, manipulation and attacks continue.

Gaza will never see Phase 2 of that abomination called an agreement because it was never going to be allowed in the first place. Lebanon sees now that much of their country is open to full scale attack and invasion despite a so called "agreement". How much of Syria will be permanently taken by Netanyahu and the right wing radicals in control of Israel remains to be seen but their foothold is not decreasing.

So my trusty Google search tells me that the Iranians should say Kos Nagu or Bokhoresh.
