There is actually a lot of information you can read in English language media, but most of it doesn't make its way into mainstream reporting. However, actual military experts and political scientists give us a pretty good insight into what's really happening. For example, this analysis from U.S. Lt. Col. Alex Vershinin retired after 20 years of service and 12 years working as a modeling and simulations officer in NATO explains that Russian strategy is not about taking territory. Russia is fighting a war of attrition with NATO. The reality is that Russia inherited a massive military industrial complex from USSR, and it is currently able to outproduce NATO militarily. Furthermore, Russia has a much simpler logistics situation in terms of shipping weapons and supplies to the battlefront. Finally, Russia enjoys air superiority over Ukraine and is able to attack deep within Ukraine to destroy supplies and infrastructure. Ukraine has no meaningful ability to do the same within Russia. Furthermore, this is primarily an artillery war and Russia enjoys a huge artillery advantage over Ukraine. This summary of the state of things John Mearsheimer is a very lucid explanation of where the war is at.

Another huge problem for Ukraine is that it's entirely reliant on western support at this point both militarily and economically. This means that Ukraine has to continue showing results to the west in order to keep support going. This is how Ukraine got pushed into the current disastrous offensive they're forced to conduct. Russians clearly expected this given that they spent the past 9 months preparing complex multilayered defences that Ukrainian military is throwing itself against as we speak.

Once this offensive burns out, Ukraine will have spent a significant amount of weapons they received from the west, and lost large numbers of their experienced soldiers. This is already happening and it's being admitted in mainstream western media fairly openly at this point. Russia is already starting a counterattack of their own in the north, and they've taken more territory in the past couple of weeks than Ukraine has taken in two months of their offensive. Russia is increasingly fighting against a depleted and demoralized army. All of this was known before the war started, Obama even quipped this in 2016:

Obama declares Ukraine to be not a core American interest and that he is reluctant to intervene in the country, because Russia will always be able to maintain escalatory dominance there. “The fact is that Ukraine, which is a non-NATO country, is going to be vulnerable to military domination by Russia no matter what we do.”

Regarding political stability, it's pretty clear that it's much higher in Russia than pretty much in any western country. The government is consistently polling between 75% and 80%, and most dissidents have fled at the start of the conflict. We also saw evidence of this when Prigozhin's attempt at a coup happened. All of the government and military immediately pledged loyalty and denounced Prigozhin. I can guarantee you that anybody who appeared to even remotely support the coup has been rooted out at this point. On the other hand, there is significant political instability in Europe, and anti war parties are polling increasingly high.

The reality is that that people care about their economic situation first and foremost. The economy in Russia is doing well, and even IMF is projecting growth. The war has little impact on day to day life in Russia. On the other hand, Europe is now in recession and people are seeing their economic conditions decline. This is the primary driver of political unrest. I expect we'll see anti war sentiment to continue growing going forward. I recall seeing that Czech president Petr Pavel say that he expects that Ukraine only has around 6 months left, at which point there's likely going to be collapse of public support in the west. Once western support stops, Ukraine will have no way to continue fighting the war and will have to accept Russian terms. Russia understands this perfectly well, and this is why they're conserving their resources and fighting a war of attrition instead of making big and costly offensives to take territory. If Russia can grind down Ukrainian army then they can dictate terms.
