If the US really wanted to flex and show their power they'd have given 31 Abrams months ago, like a day after Biden promised them and proper M1A2s with all the armour, not some downgraded crap and they'd be providing hundreds more right now

Because really if the US actually has it's supposed thousands of them then it should be utterly irrelevant if the tech is revealed since they'd still have the shear numbers.

Plus if one really believed Ukraine could destroy Russia then losing the secrets of the Abrams wouldn't really matter since Russia is the only country you'd fight a land war with anyway. Spending a thousand Abrams to break Russia would be a no brainer if it was the case.
