I saw this take (on YT) just yesterday. The gist: the US has by far the greater military, but NATO without US has much more troops and equipment that are trained and working in harsh cold weather conditions. The US may take some ports and airfields, but small European and Canadian troops can defend the land and make it infeasible for the US to take any meaningful hold.

An absolute classic!

If you solve domestic political problems with foreign policy, then you have arrived in the middle of authoritarianism.
