Why must other nations abide by our constitutional rights?
In theory it'd be great if we could "spread Democracy". Get others to adopt human rights. In reality, they just tell us to piss off and side with our enemies. Resulting in a GROWTH of genocide, torture, slavery, and all other sorts of depravities around the world. We need baby steps. We need to get nations to align with us first. So long as they are not invading their neighbors and causing widespread death and destruction, I'd settle for that. Let peace cook for decades. Then we discuss what a "next step" is for international relations. Expectations, etc. But it cannot just be the US, it should be the "free world" as a whole. Let the bloc determine how to nudge others along, where our priorities lie.
I mean, the US has relations with China....
After that, what standing do we possibly have in telling India who it must allow into its own country?
