Not a dumb question if you haven’t been keeping up.
The Steam Deck runs Linux and not Windows by default. (It can be loaded by the user if desired.)
Given their desire for a nearly-console-like experience, they put in a bunch of effort into the Proton compatibility layer to get Windows games to work here. It’s not perfect, but it really is a very good experience at this point.
I personally do have a fairly powerful Windows desktop, but the vast majority of my gaming is on Linux on my Steam Deck now.
It is very much to Ukraine’s benefit to drag out this war if the alternative is Russian subjucation.
If on the other hand the alternative you are seeking is flooding Ukraine with Western-provided weapons to the point that they annihilate the invaders and win quickly… yeah, that would be better for Ukraine than a drawn-out war.
