"But to cut off relations with an aggressor may often invite retaliation by armed action, and this would, in its turn, make necessary some form of collective self-defence by the loyal members of the League"
About this Quote
The subtext is a warning and a pitch at once. He’s cautioning idealists that collective security isn’t a dinner-table boycott; it carries real risk. But he’s also selling the League’s central bargain: if members act “loyally,” they must be prepared to turn economic and diplomatic pressure into “collective self-defence.” That last term matters. “Self-defence” frames force as reluctant and legitimate, even when it’s triggered by a policy choice (sanctions) rather than an attack on one’s own territory. It’s moral insurance language for great-power politics.
Context does the rest. In the interwar years, the League tried to deter aggression without replaying 1914-18. Henderson’s line reads like a pre-emptive rebuttal to critics who wanted painless enforcement: deterrence only works if the threat behind it is credible. The tragedy is that credibility required unity the League rarely had, and aggressors learned to test exactly that gap.
