And if they were in a country that cooperated with Russia to extradite criminals, this exact thing might happen to them.
Yes, if you violate another country’s laws, you are subject to arrest. Whether or not they can actually arrest you depends if you are in their jurisdiction or a jurisdiction that does extradition.
The US is still the sole global superpower, it is still (yes, despite Trump) largely charged with maintaining the world order that has existed since WW2. Russia is not a superpower, its reach is regional and it has few allies. You'll see a lot of varied answers in this thread, the only one that matters is this: the US can do things that Iceland (tiny nation) or Russia (large, regional power) cannot because it's far more powerful in most every regard. That's not meant to justify any arbitrary flexing of that power that the US does, it's an explanation for why the US can do it and Russia generally can't in the case of Georgia. It's an imposition of will, backed up by immense diplomatic, financial and military power. Few countries will comply with a Russian request to arrest an American executive, dozens of major countries will at least consider a US request like the one in this case.
I mean, I know it's 1999 but who knows what will happen in the years to come? /:s
What I said non-the-less is true. It's unpopular to state it, to say why things are the way they are in actuality. Sometimes reality is unpopular.
It still has lots of nuclear weapons. And probably more tactical nuclear weapons than the US does. But yes, it has fewer allies, for sure.
No, the US is not "charged" with maintaining the "world order". The US just thinks that it is. And they're so bad at their self-imposed job that the only reason why they can get away with it is that they're a superpower.
Also, after Russia-Ukraine conflict many Ukranian politicians are under a criminal investigation in Russia (and I guess Russian politicians are investigated in Ukraine). Should they be extradited too?
