We won't invade north Korea because we have too much invested in China...we are dependent on them economically now...and then of course we have Elaine Chou our Secretary of Labor that was born in China and her dad is the best friend of the Chinese president...and she has top security clearance...wow that makes me feel secure! North Korea is protected by China...
