If certain nations drop support of terrorists & their activities & begin arresting violators (as the UN wants) then no more nations need come crashing down. Had Afghanistan simply complied with our request to turn over the active alqieda, they's still be living in the 12th century & happily killing one another. Had saddam stopped his weapons programs, he could have, today, been merrily raping & torturing his civilians until the UN decided it was enough. Both had an out & refused to cooperate.
Welcome to last week. 
GONZ! open your damn eyes...Its all part of the arms race. whats the difference where the threat is coming from? We created an arms race and now there are arms out there that are going to be used against us...whether by russians or not is irrelevant . THE ARMS RACE DID NOT WORK.
