This would have been categorically true circa-1970s.
Unfortunately, US industrial vertical integration now includes foundations placed in global low-labor-cost countries.
The crash vaccine manufacturing scaling program was possible because we were rich enough to throw mountains of money (of which we have the most) at any international supply problems.
If the Atlantic or Pacific had been hostile to commercial shipping, or countries hadn't cooperated, it would have had a very different result.
> We are decimating (and then some) Russia's military by giving away second tier equipment to Ukraine, and the amount we're giving away is basically an afterthought. A one-time superpower is scraping the bottom of the barrel for equipment fighting against largely NATO supplied spare equipment.
"We" are not. Ukrainians are dying and holding their own against a much larger country, with the help of NATO surplus equipment.
20,000-50,000 Ukrainians now have at least one limb amputated as a result of the war. [0] [1]
And Russia's military is not being decimated. It's holding its own with an elastic defense, that's making progress difficult and costly for a Ukrainian army that's trained halfway between Soviet mass doctrine and Western maneuver warfare.
At some point the Ukrainians will hopefully manage to exhaust Russia's logistics sufficient to break through their defense, but that's in no way a sure thing.
