The biggest threat to the western world is whichever one George Bush picks at the time. They've not even finished the job in Iraq (or Afghanistan) properly yet (typical Americans, no change there, leave the Brits to mop their mess up yet again) and there's already rumours of them invading yet ANOTHER country. Like I said, they won't invade someone who can put up a reasonable fight, The N. Koreans might kick their asses just like the Vietcong and the Japanese did
