on a couple of destroyed Grad launchers we saw 30-year old tyres (with 'Made in USSR' written on them),
Don't forget, that Ukraine had huge army warehouses at moment of USSR breakup - including most of vehicles and ammo stockpiles moved from eastern Germany. It was happily declared ukrainian property. Later they start to beg some foreign help (financial) to safely dispose outdated bombs and artillery shells. ;) Old salt mines in eastern Ukraine was loaded by WWI-WWII era munitions from USSR strategic reserves to the top, of course. Militias visited that mines at the start of clashes and unloaded plenty of outdated firearms and ammo from there.
Russia also have a lot of mothballed older vehicles in storage facilities. I know that plenty of T-64B* with fresh engines there untouched for now, also some T-62 and even some T-55 that is cannibalized for spare parts sold for various cannibal regimes in Africa who still have some of them in service (as my friends told me). ;)
Polish farming can feed 120 million people - 3 times our population. :)
Yes, but with unrestricted access to necessary fertilizers and pesticides. I think even been put on a fertilizer diet, polish farmers will be able to feed polish population for a year or two without serious problems of soil depletion. Problem is that politicians will be unable to restrict mass exports of food to keep it for their own people.
Pork production require fodder, so at some point balance between bread and meat may be necessary to be found.
All stocks of food wheat were removed from Ukraine to the West before the conflict began, leaving only fodder wheat, from which bread is now baked (the quality corresponds to the flour class). Biden is very keen to export the remains of fodder wheat as well as the remains of last year's corn and sunflower seeds for all sorts of trifles misunderstood to be called states, which in the UN faithfully deliver votes on their agenda. He does not care much about what the Ukrainians will eat.
