The problem is that we cannot get into it. We would have to abandon them. The US cannot be drawn into something like this right now. The threat of Chinese involvement is to high.
The US has already pledged full
support for S.Korea. If S.Korea is invaded by a significant force the US (and other Nato forces) will automatically get involved, they wouldn't really have a choice.
China is NK's only Ally - Although their 'leader' has said (I can't prove this by the way; just what I've read/heard) that he doesn't condone acts of war like this; they are still Allies, and I don't think China would EVER side with the USA - Capitalist and Communists don't ally, it doesn't work.
'Ally' is a term that is not entirely accurate when referring to China and N.Korea. They are not allies in the conventional sense, like say the UK and US are, N.Korea just gain their most support from China, and recently even China has been condemning N.Korea's leadership to an extent.
Oh and China? Communist? Lol.
If the UK went to war; It'd plummet the Armed Forces into an even bigger mess; we can barely even afford to shift troops around - I think it'd be stuck in a bottomless debt-hole - and if we had a conflict with China, it'd cut 90% (random high figure) of the profits coming to the UK - we'd be permanently bankrupt.
The UK wouldn't be as heavily involved as we were in Iraq and Afghanistan. We simply couldn't be. Deploying aircraft and naval craft yeah, but we wouldn't be contributing as much to a direct ground invasion/defence as we have done in Afghanistan/Iraq.
David Cameron and William Hague would be doing a lot of talking and fist shaking though, that's our contribution sorted.
I think ultimately USA and UK involvement comes down to how much the USA cares about the alliance between them and SK - If the USA ditches on them, they'll be butt-hurt about it for years - which'll just get annoying for Americans I can imagine.
That's absolute rubbish. The US couldn't give a shit about the South Koreans. The reason why they are defending them is to protect themselves (as is everyone) from a crazy tyrant who is in possession of nukes. The whole 'protecting a free country' is just a bonus.
If an extreme case happened, and we went to war; What the conscription age? - I think I'm just about old enough to get hauled off on the front lines of war.
Presumably 18, but don't worry it would take WW3 and a direct threat to British soil before they introduce conscription again. And a direct threat to British soil is something N.Korea doesn't pose, and never could.
And ultimately, a war with N.Korea would be won by air superiority and technology not by sheer number of troops. It all depends if their leadership has the balls to push the red button if a war does kick off, if they don't they're fucked, if they do they're fucked. They're fucked either way.
