hail hallie? if south korea is critical to this, so is japan. they want to send a message that the three allies are close. any exercise, any sort of response to tests, fly b-1 bombers up from guam as a show of force but be escort bid japanese fighters as well as south korean fighters. i should add one more thing on the agreement between south korea and the u.s., at the d.o.d. level, formal level, cfc, combined forces command. if there is an attack and they do have an escalation there, general brooks, the commanding u.s. general in south korea, he would assume control of the republic of korea, south korea, of their more than 600,000 troops. so, there are a lot of formal and legalistic agreements what happens once action does get kinetic or i should say if it gets kinetic.
