I love the irony in the pitting of the US vs China, Iran & Russia, whilst talking about stoking division.

Don't corollaries to your comments also apply at a higher level globally, or is there something special about considering countries as a grouping vs political parties?

Surely they're all just games we play in our minds and people kind of arbitrarily just agree that countries most definitely exist and this is my in-group, whereas others are enemies.
