Quote from AAAintheBeltway:
In the unlikely event NK used nukes, yes, we would have an obligation to respond. I have grave doubts our current president would do so however, and so do the North Koreans, which illustrates the danger of having a weak president.
My real problem is with the concept of having a large contingent of US troops in SK as a tripwire. There is a limit to what we can accomplish. I don't see the need for us to defend europe from a non-existent soviet threat, and I don't see the need to protect a large, rich country like SK. At one point, 50 so years ago, maybe the policy made sense. it doesn't any more.
And, it is well known that we are stretched razor thin militarily. What I would do if I were Pres is let Israel fend for itself, because they can. Pull out troops, and prepare if NK crosses the line.
I know, I know, there is oil in them thar sands. So it aint gonna happen, but we cannot open another war front, and everybody pretty much knows that.
