If there is a place in the Middle East that's suited for "war with terroristic axis of evil" even worse than Afghanistan or Iraq, it is Yemen. I doubt anyone in Pentagon made a research recently about spectacular results of Roman assault on Arabia Felix and Sabaean kingdom under Aelius Gallus.

Less known cemetery of empires Yemen is, but no less comfortable and spacious. And so it was even in times when jugular vein of global economy hadn't yet been exposed to rocket launchers.
