We are trying to impose "western" ideals on countries that are, not only, not western countries but also devout anti-western 'culture' countries. In every recent case stated, from Korea all the way through to Afghanistan, the culture barrier and lifestyle of the people there is wholly different from what western norms are.
You have to go back almost pre-Crusades to find it's start where pompous European society felt that it had the one true religion while possibly just a pompous mid-east society felt that it's was the truth. Both have tenants that are similar but differ in more ways than can be easily reconciled. In any case, the West has prospered and now thinks that it will be simple to just display how great democracy is, and since our system is "So much better"
I don't see violence fixing any issues, but the only other thing to do, which "we" are rather good at by the way, is sit back and let people kill each other. To our moral responsibilities as human beings, "we" all (myself included, as well as the US, UK, European countries in general, Russia, China, etc) seem pretty adept at ignoring those on a day to day basis unless it is directly and repeatedly, some might even say blatantly or sensationally, brought to our attention through mass media. Even when it is and it's in the scale of hundreds of thousands of deaths, genocide, whatever, the outrage lasts, for most, only as long as the news coverage.
Before I can condone going into a place like this where we will do little to no good and probably more harm than good, we should figure out if we have the motivation to actually do something. We don't.
The UN is a complete joke. Every member of the security council abuses their seat of power or outright ignores the UN decree's. USA, UK, China, Russia, and hell, even the French use their vote as a bludgeoning tool, and when even that fails, they do whatever the hell they want to anyways. Out of those members I would say the UK and French are the least abusers of their spots, while Russia, China and the US are the lead abusers and also the most powerful nations at the table. Whole thing is a farce of epic bureaucracy. Countries used to be led by great men of morals, almost world wide. Where the crazy leaders where the ones who shit on their people. Now countries are led by those people who are in power and want to stay in power. It's pretty gross. Sorry for the rant.
