some countries would rather iran not do anything in the area, but that is not a matter of discussion for me. we know what he means — weapons—grade uranium. yes, i know what he means. just to finish this particular conversation about iran, then — have we seen dashed hopes of a diplomatic solution to this crisis, and is there a real possibility of some kind of conflagration or escalation or diplomatic retaliation, or whatever, against iran? i cannot afford to give up. i'm concerned at this moment because i have a problem. i'm not denying it. i'm working on it. this is myjob. another big part of yourjob is, of course, to ensure that there isn't, you know, weapons proliferation, nuclear weapons proliferation, all over the world. and another big area of worry is china. so the arms control association said this month that china's constructing at least 250 new long—range missile silos in a sign that it may be expanding its nuclear arsenal.
