Let's list some facts first.
Russia is facing serious problems in Ukraine and these are only going to get worse since there are already food shortages both on the battle front and in Russia. For instance they're running out of sugar in the motherland and soldiers sent to Ukraine barely had enough military rations to last a few weeks and we're now much longer into the conflict. Hungry Russian soldiers are trying to get food from the locals with poor results like those poor bastards who, according to the reports, died after eating food poisoned by the Ukrainians. Soon forests are going to offer much better cover for Ukrainian artillery groups and snipers and it's going to become much harder for Russians to coordinate air strikes.
Russian nuclear forces were put on high alert almost a month ago.
In response France put one additional submarine armed with nuclear missiles on a patrol mission. It now has 2 ships ready to respond. France also conducted a test of its new nuclear missile
ASMPA-RUSA brought Patriot defense systems to Europe and placed them around the border with Ukraine, in Romania, Slovakia and Poland. These systems are meant to shoot down incoming missiles.
Poland proposed an international peace mission to be sent to Ukraine, to which proposal the president of Belarus responded that such a mission would start another world war and a Russian propagandist said on national TV that
Russia would destroy Warsaw in 30 seconds with a nuclear strike, to which threats Polish president responded
"don't try to scare me or you will shit yourself" Yesterday news came out that Russia made a list of countries it wants to "denazify" and those are Poland, Latvia, Lithuania, Estonia, Moldova and Kazakhstan.
On March 25, a statement was made by Moscow City Duma deputy from the Communist Party of the Russian Federation Sergei Savostyanov, who is convinced that “the demilitarization and denazification of Ukraine will ensure sustainable security for the peoples of Ukraine, Russia and all of Europe.”
“For a more complete process of ensuring the security of the Russian Federation, in addition to Ukraine, I consider it expedient to include the Baltic states in the denazification and demilitarization zone [Литвa, Лaтвия, Эcтoния]Poland, Moldova and Kazakhstan
https://www.world-today-news.com/denazification-russia-targets-six-more-countries/Some of these countries are members of the NATO and the EU and are armed at least as good as Ukraine was before the invasion. There's also a large number of US soldiers stationed there, so a conventional assault would only mean more losses for Russia.
If they really decide to follow through with the plan the only option left for them is a nuclear attack, but that would be suicidal for Russia.
This looks like a new Cold War is brewing. I'd expect Russians to dispose of Putin before he decides to kill them all, but there's a lot of Russians who support the invasion of Europe. Half of the nation is apparently retarded and brainwashed into thinking they could win a war with NATO.
