Am I crazy

Chances are probably higher that Putin is crazy.
But trying to rationalize this, it’s probably Putin trying to show strength up to the American presidential election, supporting Trumps claim that it’s foolish to help Ukraine. After the election we will also have entered winter season, where Russia will try to rebuild.

Last I heard 1 maybe 2 months ago they were estimated to have 3000 tanks. But I hope you are right, and they are running out.

Edit:
Apparently they STARTED with about 3000, and by March this year some estimated they had 1300, so about 700 now could be true.
