Yeeeees. I'm sure the US would hate it if Muscovy decided to fuck off from Ukraine and stopped invading it's neighbours.
The entire point of eliminating Russia's military potential is to force them out of Ukraine and prevent them from invading anyone for decades to come, you know?
More tanks are always good.
The sanctions are working. But in a sense of turning Russia into a bigger NK or Iran. They don't have inflation because they immediately restricted capital exchanges preventing any capital flight. They also increased their federal fund rate by a lot, which will prevent inflation but still hurt their economy.
Russia is suffering from ammunition shortages, which is why they are firing much less compared to the start of the war.
Ukraine made more progress in the last two weeks than Russia did in the last 6 months. It was always gonna be hard. Unlike with the Kharkiw counteroffensive Russia expects it and is dug in having built up defence in depth. It was always gonna be hard, specially in the early days. More like how the Kherson counteroffensive went which took over a month of heavy fighting to get going.
I'm not aware of Ukrainians just surrendering and refusing to fight. To me it looks like they are fighting quite effectively so far.
Lastly, if you are actually worried about the loss of Ukrainian live (which I doubt tbh) than maybe, just maybe you should instead support your Biden administration and encourage them to send more material so that Ukrainians can better defend themselves.
