South Korea isn't Afghanistan. South Korea isn't Chechnya. South Korea isn't Crimea.
North Korea is also a far cry even from Russia, nevermind the Soviet Union.
So an analogy needs to be exact to be used, I disagree, but duely noted (however Ukraine and the Crimea is a lot closer that you seem to realise).
Though it's an odd point to raise anyway. The US would only support South Korea from. North Korean invasion if they had bases there?
We don't know, but with bases in country its a significantly bigger deterrent and allows fro immediate rather than delayed or no action.
Good thing we invaded all of those Middle Eastern countries and set up shop, too.
Damn I totally forgot they were all nuclear states.
South Korea would have mutual assistance even if there were no US forces stationed there.
Odd because the Ukraine thought that would be the case when they gave up the Russian nukes they ended up with, they even signed a
nice aggrement that said the UN would do just that (the US was one of the three external signatories to it), guess that one is a better analogy after all.
How did that go for the Ukraine and Crimea?
And I'm sure it would be trivial for a country with dozens of aircraft carriers and physical military presence in multiple surrounding areas to go into the peninsula to provide direct support to South Korea, if North Korea actually invaded, even if Trump had promised to pull out entirely. Which he didn't do, since all he did was say that joint exercises are suspended.
First Trump has suggested that one of his end moves is the removal of US troops (he's been banging on about that one since before he got elected - bad deal costs the US too much), and the point still stands that reaction when you have forces in country is pretty much a certanty, when you don't its not (Crimea again).
As much as Starcraft is loved in the region, I'm skeptical Zerg Rush is a particularly viable military tactic.
Really - its worked extremely well many, many times before. Again Crimea springs to mind. Oh and the US lead invasions of numerous countries were initially carried out with exactly
that kind of tactic.
That has pretty much always been true. Including before North Korea got a missile that could hit something other than their own cities, when the US wasn't terribly bothered.
It has always been true, but more so today than ever (artillery technology has moved on since '53) and the US have been 'terribly bothered' since that date, with troops stationed and exercise carried out since that year. Its also be reciprocal, with SK providing the second largest contingent of men (after the US) in Vietnam.
