Let's be clear, the US is starting it.

And when the rest of the world, like Canada, sells off their Tbonds and crashes the US economy, nationalizes US assets including patents, sells off US dollars reserves and cuts off exports - including hydro power, potash, oil, aluminum, and uranium, to name just a few from Canada - I guarantee the US will notice. Even one of these will be enough for the US to become the aggressor.

Greenland may seem minor, but where Greenland goes, Canada goes. For my country this is existential. And frankly, I can only assume you have typical American hubris if you assume the US will be allowed to do whatever they want.

Americans who enable this are entitled, spoiled, arrogant children who don't understand a) how dependent they are on the other countries, b) how a threat to their pampered asses really looks and feels, and c) that the upcoming fight for other countries is existential, and not just for more treasure. Americans are fighting and dying for more profits for their billionaires and maybe a new iPhone. They're fighting to protect a billionaire conman who fucks kids. The rest of the world is fighting for their existence. You tell me who is more motivated.

I feel like a lot of Europe didn't even bother to condemn the Venezuela thing

It won't start WW3, as Africa nor asia will hop onto the conflict.
