The US is withdrawing from its global cop role. Russia and China are saber rattling. NATO may be dissolved by Trump, at least the American side of it. Israel and Saudi Arabia are new strange bedfellows and allies. Japan and India are vastly increasing their military spending, and Japan will likely arm itself with nuclear weapons. Sunnis and Shiites are nearing a war. Turkey wants to throw its weight around regionally. International trade is very likely to be strongly disrupted and production nearshored.
We are entering "interesting times".
The Five Eyes may cooperate. Maybe.
