I'd say you defeat it one Switzerland at a time. This is really America's policy failure - we regime changed all these countries, but didn't fix any underlying problems. No country needs to be as big as Switzerland, and anything bigger than Switzerland creates a honey pot of bad incentives at the top. We should be explicitly teaching local self sovereignty in any country we clash with, including local language, local agriculture, local militia, local justice... But our own honey pot of corruption at the top means our ideals never make through to other people. So we're doing it wrong. Instead of a giant military, we should flood them with gandalf teachers that like to shoot.
