Estimates from think-tank people seem to settle on 18 months. If Ukraine can hold out for 18 more months, Russia will be out of hardware. It was 12 months for some things, and 18 months for others. I forget which was which, but they were talking MBTs and artillery pieces. They've mostly cleaned out their boneyards, and some stuff from the end of WWII (artillery) is disappearing from satellite images. That's how far back they have gone.

So, no. Russia is not a threat to Europe (sans nukes). Thank you, Ukraine, for making sure they won't be a major threat for at least a decade. Maybe two or three decades. Without shifting to a full-on war economy, it will take that long to replace their losses.

Yeah...Poland...they've been afraid of Russia for a long time, so they are among the best equipped in Europe. They are also a major contributor to Ukraine's defense, shipping lots of tanks and artillery to them.
