Institutions rarely vote themselves out of existence. Not if they still have money in their budgets. Large institutions in particular have an almost genetic propensity to cling to life even after their reasons for being have vanished. That’s why I don’t expect NATO, which will gather in Chicago later this month, to suddenly declare game over and disband – even though the alliance’s rationale has become wafer-thin. The Soviet Union is no more, al-Qaeda is a spent force, and NATO members are rushing for the door in Afghanistan. Indeed, most of Europe is cutting back on military spending, and the debt-saddled region has a diminished appetite for intervention.
