Ukraine is still relatively small potatoes unless things go nuclear. Iraq is #2. Nothing beats Afghanistan yet in money and stupidity.
Russia is now a full-fledged strategic ally of China for at least the next 25 years. Both are now working to end US lead deep state globalism. They and the BRICS are officially forming a bloc to stop trade in, and destroy the USD. The world is facing serious energy and supply chain shortages, food shortages and inflation, encouraged by China and Russia to achieve the above ends.
America's short-sighted, money-grubbing political elites, combined with psychotic, blinkered neocons and their push to absorb a corrupt ukraine will break the established US-led world order
I'd say its their biggest blunder yet.
