North Korea is South Korea's problem.
Now, what the heck is going in in Pakistan?
That's a very tricky situation... I suppose it all ultimately stems from an extremely broken and corrupt political system that's controlled by cronies, and "ruling families"... The pseudo royalty who are 100 times worse than royalty ever was because their version of democracy is forcing their way into power, ruling like a king when they are, trying to stay there as long as possible and exploiting everyone until someone manages to force them out with yet another
In Pakistan the courts are all part of the situation too.
The current guy is a military dictator, and he's actually been a lot better than the people before because he wasn't part of any of the corrupt "born to rule" political dynasties. The problem with him currently is a mix of things:
The ruling families and their supporters have gotten too strong and are stirring up a great deal of civil unrest, they want their old power back and they're using their support base to try and get it -helped in part a by naive international community and media who don't really understand that not all "democracy" is actually free and good... The other massive problem is nationalist and fundamentalist Muslim anger over Sharif letting the Americans have free reign in their territory as well as his support for them generally -with the actions against Muslims in Afghanistan, Iraq and of course support for Israel... And his restrictions over some of the crazy STUPID
things these extremist Muslim groups have been getting up to within the country. Plus there's a civil war raging in some of the tribal regions... stirred up because of US actions and encouragement (forcing Sharif to hunt down groups in those regions that have always been unstable)
And lastly, Sharif has a taste for power now himself, besides; he hasn't done with fixing the corrupt system. The trouble is that the courts wont let him stay leader of the military and STILL
be president when he goes for election, and he NEEDS
that military backing to stay in power. The courts know this, which is why they've made that decision. :)
What doesn't help is naive people dressing it up as some kind of simple problem of not having a "free democracy" at the moment... Every country is unique, and there is no one size fits all. Pakistan is in a bit of a messy situation.
But at least they don't want nuclear war with India right now like they might have done in the late 90's-early 2000's.
