It seems like they are running out of time.

They are running low on war material and are basically going from factory to front, but their production rate is 1/10 of their loss rate. We’ve already seen drops in losses (like artillery systems) compared to months ago, as they don’t have replacements, and have to lower the quantity they use.

Their economy is imploding (interest rates just hit 20%). The non-defense industry can’t pay for their loans and 1/3 of companies are at risk of bankruptcy in the next 6 months. But they can’t stop the war or their economy (held up by defense industry) will crater into a deep recession.

Their population is indifferent to the war, and doesn’t want to sacrifice more to help fight it. So unlikely to accept another mobilization or increased hardships.

And Ukraine just got approval to use foreign weapons in Russia.

So, yeah, Russia is probably a bit stressed at the moment.
