agreement, it could stay. if it wanted to leave or go in between, that was up to them once the agreement was broken. sort of like when the russians cheated on the inf treaty, the u.s. is free to respond, get out of the treaty, do whatever it wants. that's where iran is. they are trying to put political pressure on the europeans and on the united states. my hope is that right now what we have is maximum pressure versus now knew nuclear provocations. we know that story. we did it for years in 2000s and it didn't go very well until we had an agreement. i hope that all parties can back off and find a way to get this back to a stable situation before it gets worse. mike: does making these threats with the nuclear program play well for the regime in tea ran? -- tehran? >> it does. it helps the hardliners, it undermines the government. there are a whole bunch of iranians who in years past said listen, let's have an agreement with the u.s. the supreme leader finally said okay, i don't believe it. i don't trust them, but fine.
