A military answer to North Korea? Not likely.
Defense Secretary Gates, off to Singapore for a regional security summit, says US sees no 'crisis' in Pyongyang's 'very provocative' display of force this week.
The US has about 28,500 troops on the Korean peninsula, including more than 16,000 soldiers guarding the "demilitarized zone" between North and South Korea. On Thursday, the US and South Korea raised the threat level there to its highest point in 2-1/2 years, in response to Pyongyang's actions.
But there are few military options to counter North Korea's move, and analysts say most of them would seem aggressive and only ratchet up the tension.
"As North Korea escalates day by day, you don't want to be provocative," says Nicholas Szechenyi, a fellow at the Center for Strategic and International Studies, a think tank in Washington. The US military should sit this one out because this is a time for diplomacy, not a show of force, he says.
