Well presumably most people don’t actually risk their lives for the cause. They risk their lives for the prestige, power, money, or whatever. Fighting in a war is a good (but risky) way to gain respect and influence. Also there are social costs to avoiding the fight.
In terms of national self-interest, yes. But they weren’t causes that I’d personally risk death for.
I’m being inconsistent; I’m using the “national interest” standard for WW2, and the “personal interests” standard for these wars.
