America isn’t ready for another war — because it doesn’t have the troops

Coverage of the wars in Ukraine and Gaza is mostly dominated by talk of weapons. Reporters and analysts focus on suicide drones, on shell deficits, on targeting algorithms. But for all the attention devoted to modern weapons and munitions, both conflicts are proving that modern war still comes down to people.

In Ukraine, battlefield deaths on both sides were estimated to number more than 200,000 by the fall of 2023. Though US weapons and munitions have been critical to Kyiv’s war effort, it was territorial militias and hastily trained citizen-soldiers who helped save Ukraine from total conquest in 2022.

At the same time, it was a partial mobilization of more than 300,000 troops that stabilized Russia’s lines and prevented a potential collapse in late 2022. Today, the war has settled into an attritional slugfest, with both sides desperate to keep the flow of new recruits going, to the point where ranks have opened to older men, women, and convicts.

The situation is much the same in the Middle East. On October 7, Israel’s heavily automated Gaza perimeter was breached by well-trained but low-tech Hamas terrorists. The attack was eventually repulsed by conscript soldiers and armed volunteers — even in the “start-up nation” that prides itself on its technological prowess, security depends first and foremost on people. Similar to the Russian mobilization before the invasion of Ukraine, the immediate calling up of 360,000 reservists enabled Israel to conduct its campaign against Hamas and deter other non-state foes in the West Bank and Lebanon.
