“Yes, if attacked, Poland would kick Russian butts more.”
With what, their WW2 Calvary? They didn’t do too well then and like the rest of NATO didn’t bother with having military, since the Cold War was ‘over’.
In any case, it’s far more likely that once Donbas is fully liberated, Poland will cut a deal with Russia to carve up Ukraine and get Lviv back, at least per the recent rumors.
The calvary were quite effective when used as Poland did against the Germans, that is until your Russian buddies stabbed them in the back.
Poland has F-16s and Leopard 2 tanks and is going to buy F-35s, M1A2 Abrams tanks and HIMARS rocket launchers among others. Unlike some other European countries, Poland has quite a strong military. These days, Poland would defeat Germany.
