> Every Russian soldier, vehicle, or round of ammunition expended in Ukraine for increasingly diminishing returns is a Russian soldier, vehicle, or round of ammunition that will never harm a NATO member.
Sure, and it's also 10 dead Ukrainian soldiers that will never return to their families, and a few thousand people living an extra day in war, and a few hundred more Ukrainian refugees that must be subsidized in Europe, a few dead Ukrainian civilians that die of Russian shelling, and a few dead Ukrainian civilians in Donbas that die of Ukrainian shelling, and the further demilitarization of both NATO and the US as they run out of munitions and equipment to send (and lack the industrial base to make up for the shortfall). It is also a few more percent lopped off of European GDP as the continent plunges into a steep recession due to the energy crisis.
It is only by weighing of the lives of the people in the conflict at zero that the U.S. justifies prolonging this proxy war and continuing to arm and subsidize Ukraine.
It is truly willing to fight Russia until the last Ukrainian, and until Europe is completely de-industrialized.
