I suppose that's one of the UNs weakness in that they lack the ability to enforce a lot of conventions.

A world government with a force would be an interesting concept. Corrupt African states has lead to their citizens fleeing to Europe with EU solutions being band-aids like giving Libyan coast guard ships and money to prevent the ships from leaving Libyan waters, the better solution would be to fix corruption and help development in the refugees' home countries, but the EU governments can't do that, can they (giving the governments money would just mean the leaders would be able to afford a new villa and a few more Mercedes Benzes).

They could directly invest in infrastructure (coupled with suitably sized bribes, which can be kept to a small portion when done directly), which is what China is doing.

But they'd get accused of colonialism if they actually tried to help directly like that (and perhaps it would be true). So they're left in the untenable position of dealing with mass migration or funding warlords.

How many Libyans go to Europe by boat..?

Quite a lot: http://www.euronews.com/2017/06/26/more-than-30-migrant-boat...

Not all of them make it. The vessels aren't particularly seaworthy, and they're not allowed to dock, so effectively they dump their passengers in open boats and rely on the coastguard rescuing them and taking them to Italian soil.

We had that- we called it colonialism. And for suggesting that you will be racismed.

It worked for those cases where US interests aligned with UN interests. For everything else, not so much.

There is no evidence that UN is a U.S. puppet.

Russia used SC veto 7 times just in last 3 years. The last time USA has blocked any resolution was 2011.

What I meant is that military intervention backed by the UN is more likely when the US wants said military intervention.

And to put whom in power instead of him? It doesn't work.

It's been done before by the UN: https://en.wikipedia.org/wiki/Cambodia#Vietnamese_occupation...

TL;DR: Regime in cambodia genocides about 1/4 of its population between 1975-79, is removed from power by Vietnam. UN helps recovery from destruction of society by previous govt & transition to new govt which after some initial chaos stabilizes. It's still not a proper democracy, but at least it isn't genocidal.

Considering the extremely difficult circumstances (a genocide so bad that it destabilized society & vietnam being an authoritarian regime), I am actually impressed by what the UN managed to pull off.
