“Canary in the coal mine” is well put. I believe part of the war in UK from China’s standpoint is to bleed-down US and western stockpiles. We cannot make anything any longer.
USA has approved 22 arms deals to Taiwan, and we are struggling to supply 3 of them. Israel PM said the Biden admin looted 250,000 artillery rounds from Israeli stockpiles to give to Ukraine.
When Trump kicked Nato in the fanny to live up to its treaty responsibilities, France had about a week of aircraft munitions on hand.
We don’t have a lot, it’s going quickly, and we struggle to make more.
