You're acting like a million deaths is the same as 100,000 deaths. I'm not saying a mono-polar world is sunshine and roses. I'm saying a multi-polar world is worse. I'm giving you numbers to back that up.
It's not like either of us is going to change the course of the world. It will likely go in the direction of a multi-polar world because the US is on the decline. You shouldn't be so naive as to think that you should be preparing to celebrate world peace breaking out when there's a multi-polar world. You should be prepared for world war.
Some the things you listed are just the start of that. Syria was not exactly aligned with the West. It was aligned with Russia and Iran which are pushing for this multi-polar world you seem to think will be better. Half a million people were killed in the Syrian civil war. You should expect more of that in a multi-polar world. Ukraine is another example of Russia trying to become a Great Power in a multi-polar world. It's at least a million dead and counting in that one.
