as you leave office, how much of a disappointment is it to you, that iran still has an active nuclear weapons program? well, i think it is an ongoing problem, for is the world. not just for the united states. i think that iran with the nuclear weapon, is extremely destabilizing and i think it could precipitate a nuclear arms race in the region, and, i think we haven t thought through all of the e haven t talked enough about the consequences of iran acquiring nuclear weapons. so, i think our position, that we can t accept that, as an outcome is the right position. and, my hope is, that we can, you know, as the president, his predecessor said, all options are on the table and my hope is we can find a peaceful way to persuade these guys this is not in their interests. chris: finally, i want big-picture reflexes frctions f you, 45 years on and off in government service.
