This is an interesting take.
Ukraine's defense industry says the fight against Russia has shown it that the West's approach to weapons is all wrong
During the Second World War, the Germans made some highly capable tanks. The Panther was their most capable main battle tank. The Germans made 5,995 of them.
The comparable American tank, the Sherman, was not as good as the Panther, but it was easy to maintain and fix. The US made 49,000 of them. The comparable Russian tank, the T-34C was comparable and the T-34/85 were arguably batter than the Panther. The Soviets made 84,000 of them.
Total those up and you have 133,000 Allied tanks vs 5,995 German ones. Throw in the German Pzkw Mark IV tank production (8,500) and the Germans were still outnumber over 9 to 1 in main battle tanks.
Spoiler alert: German lost the Second World War quite badly.
NATO would be wise to bear that in mind.
There is obviously a limit. If you have the worst tank in the world, and you opponents have bows and arrows, even one very bad tank will always win. The question revolves around how much better is country A's weapons vs Country B's weapons, and how many each has. The Russians have traditionally come down on the side of lots of decent weapons and the US increasingly on the side of very very few weapons of very very high quality (and huge price tag).
