ELI5: Why can't we save the North Korean people?

I was just thinking, the UK and USA have intervened in Other situations where there has been worry about the lives of people in that country. Is it really all about oil? Do they really not care about the people suffering there?

Edit: thank you all for you're brilliant explanations. I understand why we won't interfere, as sad as that is. I guess we just have to hope that somehow the regime collapses on it's own, impossible though it seems as the people of DPRK are so brainwashed the won't revolt.

Because North Korea has the largest artillery force in the world scattered along its border aimed at Seoul. It's probably the most credible and effective deterrent in the world next to the US and Russian nuclear arsenals. Any military action would result in the destruction of a densely populated city that is one of the world's most important economic hubs. The artillery can't be destroyed in a first strike, it's far too distributed with a significant portion of it being mobile. Nobody wants to be responsible for provoking North Korea, so we leave them to torture their citizens in peace in hope that one day they'll collapse.
