A commenter over at Americablog has a good explanation about
the current Iranian effort to switch from trading dollars to euros. He wonders if the missiles will start flying in March, when the switch is supposed to happen.
I knew about Saddam's efforts in this direction from reading Crude Politics. We could be in for a major depression. Or another war. This is probably why Rumsfeld ordered the ICBM warheads switched from nuclear to conventional.
