Who said ever?
Marching on Moscow in September is a fool’s errand. If it were June, you’d have a better chance.
But I think we both know anyone marching on Moscow will be incinerated right as they enter the city. Along with the rest of the western world.
More to the point, this very discussion is the root of everything we are seeing unfold. The Russians have been catastrophically invaded from euros many times.
They are deeply suspicious already from this background. So NATO expands west right up to their border.
Then we see discussion on how best to invade and capture Moscow.
This confirms for them everything they fear and is reason numero uno they insist on a buffer zone between they and nato.
If Russia ever forces NATO to take it to Moscow, then it will be done.
The only strength that Russia has, is that it is one of the European nuclear powers, but that would be their suicide.
Russia will submit to strength, now is no time to be surrendering to them and assisting them in becoming the powerful USSR again.
