WW3?

Probably/hopefully very unlikely, but if WW3 would happen pre-singularity I think it could look very similar to now. With the war in the Ukraine, the situation in Gaza, the tensions around Taiwan, and the perceived weakness of the US, this seems like the most dangerous time for the world since the end of the cold war.

I'm trying to collect questions here that would best signal moves to increased or decreased risk of WW3.

(@Manifold: It would be nice to have a comment section and/or direct messages so that people could suggest good questions.)
