Out...redeploy closer to Taiwan and allow SKorea to act big on its own defense like they talk...Certainly they can defeat the poverty stricken Nks.
We can't strategically walk away from South Korea. To leave would be a horrible overreaction to the idiocy of a politician.
Redeploying closer to Taiwan might start a war with China, by the way.
"Certainly they can defeat the poverty stricken Nks."
I don't know about that. The North has been spending virtually all of its money on the military and starving the citizens. The South has been spending all of its money and foreign aid building factories to make automobiles and electronics. It's typical of what countries do when the US helps them: They are willing to take the money and be nice to the US as their economy starts to grow. When things are going fairly well, they are still willing to take the money but they feel free license to criticize the US and vote against the US in the UN. Once their economy is really rolling along, they are still willing to take US money but they are completely adversarial and essentially enemies of the US.
Best bet is to let 'em duke it out then take out whoever is left standing. Japan could use a little more space.
