The West’s New Isolationism: Comfort Masquerading as Principle
In the 1990s, Western foreign policy elites convinced themselves that history had effectively been tamed. Dictators would liberalize once they had McDonald’s and broadband; expansionist wars were relics of black-and-white newsreels. The “end of history” cliché was mocked, even as it quietly shaped the worldview of the people running things. Now that revisionist powers are openly testing borders, from Eastern Europe to East Asia, we’re learning how expensive that delusion really was.
What’s striking isn’t just the aggression of Moscow, Beijing, and Tehran, but the fatigue of Washington, Brussels, and London. We are living through a paradoxical moment in which the publics of the richest, safest societies in human history insist they are “exhausted” by global responsibilities they barely shoulder. Burden-sharing has become burden-avoidance: every crisis produces a new vocabulary of pretexts: “quagmire,” “escalation,” “provocation”, deployed mainly to justify doing less.
Much of this new isolationism is carefully wrapped in moral language. Demands for supporting allies are recast as “forever war” addiction; maintaining deterrence becomes “militarism”; enforcing red lines is smeared as “imperial hubris.” It’s an appealing narrative because it flatters the audience: you’re not looking away out of comfort or cowardice, you’re bravely “breaking with failed paradigms.” That this moral awakening happens to involve cheaper energy, fewer trade disruptions, and no difficult trade-offs is, we are assured, purely coincidental.
But the world is not obligated to respect our self-serving narratives. When revisionist states succeed, they don’t just redraw maps; they rewrite the rules that kept the last 75 years, for all their crises, comparatively stable. We can debate the boundaries of intervention and support—that’s a healthy argument. What we can’t afford is the fantasy that retreat is cost-free, or that our inaction is an elevated form of wisdom. Nature abhors a vacuum; so does geopolitics. If the democratic world abdicates, others are already queued up to inherit the stage, and they are not interested in our preferred ending.
