We are obviously making a tradeoff with quality vs quantity. Will we have enough quality weapons to overcome their limited quantity? Who knows. Given the current state of our foes, that seems likely, but you never know until the **** hits the fan. I will say, that drones will move the needle towards quantity in way we haven't seen since the Cold War. Our drones will likely be of higher quality than our peers, but it is also a numbers game. Unfortunately for our foes, our investment in battlefield networking across multiple weapon systems will lead to much more devastating efficiency for our drones.
It's more about the type of conflict. The Cold War was designed and planned to be a continental land war of attrition. Ukraine is currently fighting the war NATO prepared for 40 years ago. Luckily, for us and Ukraine, the Russians didn't really advance much in those 40 years aside from air defense platforms. Thus, we can defend Europe and dramatically weaken the Russian threat with our outdated and mothballed Cold War assets without risking American lives. A major, major geopolitical win for the West.
The vast majority of those weapon systems (tanks, artillery, IFV's, etc.) will be completely useless in a war against our current biggest advisory, China. A potential war with China over Twain will be fought via the naval power, air power, drones, and missiles/anti-missiles platforms.
