It's expected. Look at the losses when Russia was attacking...Massive losses also. Ukraine would be foolish to think the same won't happen to them...

This war will continue as long as USA keep supplying weapons. Or till Ukraine ran out of men.

The biggest problem Ukraine has is that weapons supplied is dwindling... Basically only USA is still supplying on borrowed money. Germany is supplying a little more. The rest are just like token amounts for courtesy purpose.

This war is actually boosting economies of countries like Iran and North Korea.. by supplying weapons to Russia. They are buying most things from china instead. Then some are getting cheap russian oil... Lol...

So, this war is a strange war. Russia sells oil and gas to xxx countries who in turn sell them to Europe. Europe is basically funding this war. Unless oil and gas in Russia runs out, it will never stop.
