Russia still have the opportunity to use tactical nuclear weapons. I still believe there is something big to happen. Like Taiwan invasion or nuclear or chemical weapon use. There will be a major twist to war were Ukraine will blame on US for backstabbing towards the end of the war.
For Putin, meeting his goals is his ultimate objectives. He don’t care how many equipment’s destroyed or troops killed. For Russia its show off power, control of the region and clearing the arsenal to make way for the new are the priorities in the war. For US its a business in the name of protection they right now might have got lot of orders from other Russian neighbors including Japan. Why didn’t US asked its allies to send patriots instead of S300? If it gets destroyed, their business plans will get impacted. Ukraine is the scapegoat of this war. So if Russia wants to end the war, they can either create a new flash point which is of more interest for US(e.g:- Taiwan) or bring the war to abruptly end via tactical nuclear weapon use. Their priority is Donbas and securing Crimea permanently. Once that is achieved only we will know what are their phase 3 plans. Since Ukraine lost a lot of territory Russia is already into a long term war where they need to change the strategy again after the phase 2 culminating point (~90 days). So they can end the war with a strategy which will end the US interests in Ukraine. The threats from Russia to baltic area is just a mockery. Even if Finland and Sweden joins NATO, Russia will not attack them as they already have nuclear weapons in baltic area. Finland/Sweden cannot be compared to Ukraine w.r.t Russia’s interest. At least my prediction on culminating point for 40 days went correct as Russia changed the strategy in ~38 days instead of a stalemate or more loss than advantages. Russia moved out of Kyiv and changed strategy on Donbas only. The recent disclosure from the Chechniyan leader points that Russia has intentions to get Kyiv and remaining part also conquered. So a phase 3 is also expected.
“Russia shot down a cargo plane carrying foreign aid weapons sent to Ukraine over Odesha” That’s the power of S-400. Striking at enemy aircraft from your own controlled territory. Possibly Moskva sunk by a foreign made anit-ship missile than Neptune. If it was Neptune they don’t need 50 days to try.
