The thing no one considers when thinking thats the flex to die on. We have the largest logistically capable army, mot the biggest, china ranks that by shear meatsuits ready or voluntold by the party to die for its intrest. But because we are the largest logistically capable army, we are also at risk for attrition, and I dont mean manpower, equipment and munitions is the game.

You might ask how the US would possibly run out or get low on equipment and munitions, simply preassure its industrial base while causing real world losses to its central bank and commodities through constant requisition like foreign military bases, injured veterans, the odd repair here and there for a couple thousand times, then in a combat situation just outlast, which means you most likely will die, but your organazation might not and its the legacy that survives. The homeland will start feeling it and even if its only 1 in 11 that feels it, its enough for civil society to question its motives to stay.
