ELI5: Why hasn't anyone actually attempted assassinations of the North Korean leadership?

With all this talk of how The Interview is now cancelled because of North Korea, I'm curious why it hasn't been attempted? Their citizens are basically starved prisoners, and there are executions frequently. No one is really gaining anything from them, except for maaaaaaaaaybe China. So why has this not happened?

North Korea is controlled by a bunch of psychos, but in the grand scheme of things, are powerless. They like to make a bunch of threats and bomb a few South Korean ships and islands, but don't actually constitute much of a threat. However, if you try to attack North Korea, you're gonna cause a bunch of problems. They have medium-range missiles that are capable of hitting South Korea and Japan, even though they probably don't have the capability to launch a nuke on these missiles. Also, North Korea has a lot of very poor people. If the country collapses, you're suddenly dealing with millions of refugees.

TL;DR: It's easier to ignore North Korea than to actually fight with them.
