What do you think Obama will do now that North Korea has openly attacked South Korea?
Yeah, it has been 50+ years and we are still in Korea. No exit strategy for there either.The "domino effect" is no longer a valid excuse for a war and South Korea has nothing we want. The US will let them fight it out. We won't take action until N.Korea builds an accurate ICBM or starts turning out quantities of weapons grade plutonium. We can't figure out how to get out of Afganistan, yet alone figure out a stratagy for Korea.
