Since america pivoting from focusing on russia to focusing on china is all but guaranteed, we should probably discuss what to do with asia. As a european I think america should create a separate alliance since we would likely never accept being forced to defend some dnb country on the other side of the world, meaning that only japan would be allowed to join in practice if we tried expanding nato. If america created a new alliance however, countries like south korea, the philippines and possibly india may be able to join as well.
