Simulations of a conflict with China consistently show the US depleting its high-end munitions in about seven days. The industrial base then requires two to three years to replenish these stockpiles, revealing a massive gap between military strategy and production capacity that undermines deterrence.

The English weren't led by incompetent occupiers. John, Duke of Bedford was a wise, feared, and respected administrator who spoke French and maintained a standing army—a rarity for the time.
