It's also worth noting that Russian military industry is state owned which makes it inherently cheaper than privatized European industry. Also, Russia is absolutely not running a war economy. People who keep repeating this have no clue what a war economy is. Military spending in Russia is around 7% GDP. A war economy was what US ran in WW2 with 40% GDP being the military spending.

The Europe may realize that it can't rely on US anymore, but the reality is that Europe is largely deindustrialized and lacks energy independence. Production of things like steel is very energy intensive, hence why the UK is no longer able to produce steel, or much of anything physical domestically at this point. Other European countries don't fare much better. This was perfectly illustrated by Europe failing to meaningfully ramp up artillery shell production over the past three years. If Europe can't even make basic things like artillery shells, it's in no position to contest Russia militarily.

All this makes what Europe will or will not accept completely utterly irrelevant. Europe will be dictated to. It seems like Europeans are still suffering from delusions of grandeur, but the reality of the situation will start sinking in soon enough. Rhetoric alone gets you only so far.
