The Ukraine war is the cheapest, most affordable, most effective war the US has ever fought. They get to kill 1000 Russians a day using a proxy state, and Russia is so fucking dumb they actually think they're gonna win. The US kept limiting the arms they gave to Ukraine to bait Russia into going all in, which they did, and now the real weapons are going to start arriving soon. Not just Leopard tanks and Himars rockets, but F16s and Abrams tanks are coming.
Also, apparently the US is giving Ukraine remote anti-tank mines, they launch a bunch of remote armed mines and shoot them behind an approaching enemy, this blocks their retreat. So if they needto withdraw then all the tanks get clogged up on bridges. Russia is really screwed now.
