US taking over Greenland after Venzuela. How will it impact stock?

All my pension is in SP500.

Terrified ad it might start a cold war between eu and US.

It might trigger a chain even where China takes over Taiwan. Russia takes Ukraine. Are we back to 1940s?

We never learned from 1914 and did it again in 1942. Its not even 100 years yet and we are back at square one. This time when every country is nuclear.
