Can We Sue Germany for WWII?

[InquiringMind]

I think that since there isn't a higher authority shared by the US and Saudi Arabia to oversee the process and enforce the judgements, the power of the law only goes as far as the Saudis are willing to cooperate with it.

What are they going to do, come move the buildings they own here over to SA? Perhaps seize Chase by force of arms?

I don't think you're thinking this through. The interconnection of the world's economy means that every country worth mentioning has hooks on every other country worth mentioning -- especially America, a favorite investment destination. We don't need Saudi cooperation to impound funds generated in America by Saudi investments.

But then the Saudis could decide to stop selling us oil, and then we'd have a real problem on our hands.  What you've described is more of a cold war, not a lawsuit. And I really don't think that pissing off Saudi Arabia is a good idea.
