During the first cold war conflicts happened outside of the super-powers:
- Vietnam ๐ป๐ณ and North-Korea ๐ฐ๐ต๐ฅ๐ฐ๐ท
This time conflicts will happen in Siberia, Africa and Middle east. I also think Indonesia and Pakistan will be center of major conflicts between China, India and the USA. These conflicts will costs some millions of lives, but not touch the empires heartlands, so it will not get nuclear again imo.
