Yes, "quantity is also a quality of its own". I don't see that the U.S./EU effort to crush Russia economically has failed.

Who can outlast who? You say Russia can outlast the U.S. in the weapon production necessary to take Ukraine in 12 years. Can Russia survive 12 years economically? The U.S. can. The U.S. hasn't even broken a sweat funding the war these past 3 years. We'll just have to see!

I believe you underestimate the technological drone advances of Ukraine and its allies.

Yes, there's a lot of stupid stuff said out there, like Russia wants to take Europe, but a waste of our time? ;)

I don't see any flaws in your logic. You believe it will be military strength that will give Russia the win. I believe it is economic strength that will give it to the U.S. Though, of course, NO ONE wins at the end. The elites stop fighting and forget the dead.
