I don't believe the US does nothing for their security, certainly in the case of South Korea and Japan I think the US has been both an asset and a burden. I'm just not certain that what the US does is entirely necessary, meaning I don't think it's impossible for the world to go on without American interference and it shouldn't be a unilateral decision on the part of the US to simply opt out.

If the US has treaty obligations that require its military engagement, then those need to be upheld, or else the US should try to renegotiate them. Otherwise, even if the security situation is made worse, the US should respect other countries' sovereignty if they want them gone.
