I recall Melech David was asked whether he prefers a natural disaster – pandemic, climate change, or the war. He preferred the natural punishment as there is no limit to human cruelty once it is unleashed.
20th century illustrates it well with two WWs, communists and Nazis. There were lots of “useful idiots” in USA and Western Europe who would protest every Western action against Commies, but not other way around ….
I don’t think anything changed much – if we can decrease advances of Russia/China/Iran/Norks and leave more dirty air to our children, that’s Ok. So, if we can have Canadian oil instead of Russian, this is OK. If you want to reduce pollution in a smart way, you can, for exanple, put a tariff on everything China is producing using energy from dirty coal and slave labor in North Korea. Just keep your priorities straight.
