Korea..an example?

Recently there are signs of Americans getting sick and tired of protecting the “ingrates” (Germany and S.Korea comes to mind). Some Americans are suggesting the US to pull out of S.Korea and see what happens on the basis of many S.Koreans wanted the US troops to leave or the S.Korean government uses the American’s “interests” of stability in the Far East as a chip for internal political motives. But, some Americans suggests to leave S.Korea is to show signs of LACK of leadership that has been the trademark of the US during the cold war. So, what is your opinion on US troops in S.Korea?

Personally, i think the US should pull out from the Soeul region and only have a small amount of troops in the southern city of Pusan. The US should let S.Korea engage the North as it likes since i believe the current crisis had already engrave the necessity of missile defence in the face of Japanese leaders. Without the current crisis, many leaders in Japan still refuses to belive in missile defence for the sake of trying not to antagonize the Koreans and Chinese, now the Japanese got their legitimacy for such as system. Two results, if deplomacy works then the Koreans get to reunite and Americans won’t be viewed as holding Koreans back. If deplomacy fails, then S.Koreans have to taste the responsibility of their own defeat and no doubt American soldiers will come once again. But, the difference is that Japan’s deterence in the form of missile defense against the N.K. is there irregardless of the outcome. I don’t trust the N.Korean leadership at all and i believe the South will bite into a bitter pill, then they’ll realize the amount of American sacrifice. But, of course we’re dealing with real lives and hopefully the best will turn out. What’s your take? by the way, before the pull out of the troops in S.Korea, we should leave Germany asap, why in the world we even have troops there even to this date? It’s wasting our resources and tax payer’s money.
