Well, to be fair, there is a specific reason that NO NATO country will sell (or give) their latest and greatest weapon systems to Ukraine. Please reference the pictures of the knocked out Abrams (along with others of Leopards, Bradley’s, et Al). It is a thing called “technological security.” One just doesn’t send their best and highest technology to a situation where the technology can end up being looted!
Case in point, when I was stationed in Japan as a mechanic on USMC F4-J Phantom II in 1970, the USN wouldn’t allow Us to send any into Vietnam because they were “too new, and would constitute a security risk!” And those would have been used in Direct Support of our own Marines on the ground!
