The two person is not the same .
You covering lot of opinion and view under one hat, and consdiering like you see the writing of one person, not hundreeds.
This kind of "Russia inflict the highest losses to the NATO/Ukrine" is the most prelevant view on the forum, considering that they haven't move too much in the past few month, but inflicted huge losses to the enemy.
The current play is only a version of this.
This time the best NATO trained man with the best NATO equipment doing the push, and the thin russian defenders just let them bleed.
If they loose more territory, but the NATO equipment destroyed, and best part of the NATO trained troops, then it will be easier when the mobilised soldiers turn up .
As I see it the only important thing is for Russia to keep the Crimea land bridge in a serviceable state. Everything else is expandable as long as Ukraine is paying enough for it.
As many have complained why Russia does not just strike the bridges at the Dniepr, Russia retains that option. Ukraine is geographically encircled in its Eastern territories by Belarus and now the Russian land bridge to Crimea.
Should Russia bet it all and sends the whole army to land lock Ukraine and push through from the Belarus direction, any forces in Eastern Ukraine will be trapped. In that regard, the whole east is expandable because it is easy to gain it back when a full scale assault starts.
On the other hand, if Ukraine can break through the south and destroy the land bridge, then it is probably in Russia's interest to immediately sue for peace with minimal gains. Without the land bridge, Russia is effectively back to square 1.
And is it fair to just admit that Russia may not win this war, and this conflict may drag on for years with the only possible exit strategy being a negotiated truth. The threat of using nukes is a sign of desperation. And when I mention how China is boxed in from helping Russia (considering how a victorious Russia in this war is vital to Chinese interests), people here said: " real friends don't ask each other for help".
Russia winning is not really necessary for China. Just like EU losing big time economically presents opportunity for US, so too does a weakened Russia present opportunities for China.
An Ukraine leaning truce is fine by China. The economic damage to US "allies" is alreadg done. Russia's economic reliance on China has greatly increased. If China does not send its own volunteers to Ukraine, China's national prestige has not been tarnished, because they retained neutrality.
There is no negotiation. Ukraine said it won't be satisfied with the February 2022 borders or a return of Crimea and Donbass now. They've already declared the intent to invade Russia. Their surrender terms are already laid out elsewhere on this thread and is basically an unconditional surrender of the Russian government.
So Russia cannot surrender and is literally in a state of total war for national existence right now. They just don't know it yet.
It is just sleep talk by Zelensky, if Crimea is threatened and Russia can't conventionally defend it, nuclear ultimatum will come out. And Ukraine will be happy to take any deal where most of or all the Donbass is theirs.
