What hubris? They did what they needed to in supporting Ukraine and it's been incredibly successful, given popular sentiment was Ukraine would fall within days of the invasion. Are you just going to ignore Russian hubris here, invading a giant sovereign nation and exposing the weaknesses in your military along the way? Lmao
Given that Russia could always go scorched earth on Ukraine with heavy bombing campaigns like NATO countries do on their targets, they could have made Ukraine "fall" within days if destruction was their aim. We should all be thankful that their approach has been less brutal and barbaric than those of the EU, UK, and US.
We are now seeing small-scale examples of what was always on the table re: the Ukrainian power grid. It could have been gone literally overnight at any point in the last 2+ years.
It has been clear for some time that the RF is resigned to a slow meat grinder for Ukrainian troops, as any real negotiations were taken off the table by Ukraine's real masters in the US and Europe.
This literally happens every years, and people don't seem to notice a pattern apparently. Russian government gets more revenue domestically from doing exports with a weak currency.
Give them a minute they're going down the list of capital E Economic platitudes to say Russia is for realsies gonna collapse tomorrow and China the day after
