“ We blew those things up basically weekly in WW2 and the Germans just rebuilt them every time.”
Yes they did, but it took time and manpower. At the beginning of 1945 Albert Speer reported to Hitler that total industrial production was about 20% less then anticipated do to allied bombing. Adolf Galland wrote in his memoirs about the lack of fuel, till they very end, for the Luftwaffe. The Americans in the Philippines were forced to surrender in 1942 do to lack of food and ammunition. The Union Navy implemented the Anaconda Plan to strangle supplies to the Confederacy. The Germans almost defeated Britain not with the Luftwaffe but with the U-boats that were sinking transport ships. Look at Nepoleons defeat against Russia. As best as I can recall the Russians never engaged the French in any major battle they just practiced the scorched earth retreat and left the French to starve. An Army produces nothing, grows nothing, it is ultimate consumer, it must have supplies to survive. p>

You list a lot of very specific situations which are not at all analogs to the current situation though. As I said before, Ukraine won’t run out of any of those necessary resources as long as Russia is foolish enough to continue threatening the West. We can easily supply Ukraine as long as we supplied Russia to fight the Germans in WW2, and that will probably be quite long enough to make reduce the Russian army to a level that they will have to choose between continuing to attack Ukraine and being able to defend the rest of their country.
