>> well, the iranian leaders have been really cautious. you might have noticed it. while there have been missile tests from north korea, in iran in the recent months, there hasn't been a single missile test. so it's clearly -- decisions have been taken not to put more fuel on the fire. at the same time, the iranians are seeing the saudis spending a lot of money in towards loving groups in the united states, working on media. making reforms back home, even. in order to also improve their image abroad, if you will, and also make iran look bad in some cases. so there is a growing worry that there might be an escalation with the saudis. at the same time, a lot of people are saying, saudis, yes, they buy a lot of american weapons. but they haven't been able to achieve very much with those weapons in yemen.
