Russia had a pass, when it withdrew from the North, could have said, really sorry, military exercise went crazy, we shot a few generals, all good, here's some free gas.
But no, now they literally want to go all in, tank v tank etc. So even though they have been met with savage resistance, and those at the top now know this, they STILL want to have another go. You have to question the mental situation of the leaders in this.
So yes, I would literally provide everything Ukraine wants. There should be no problem sending the older LEo2 and Abrams, and if they want them 100 challenger 2's from the UK. If other countries still have T72 etc, then yes these would be easier to use, but the old NATO countries should not hide behind the newer ones, on this issue.
I love all the games set in Russia,
@HAL9000 mentioned Stalker, love it - AS A MAKEBELIEVE f***ing GAME! Not in reality, and this is what Russia has created in the areas it invaded.
