> For example, NATO doesn't force countries to join, and doesn't invade countries if they want to leave or join another alliance. See France.
France never actually left NATO the organisation – they just withdrew from NATO's military command structure (1966), only to later rejoin it (2009). No country has ever sought to leave NATO the organisation. There is a clear procedure for doing so (Article 13), but no member has ever invoked it.
Interestingly, Article 13 actually says that prior to 1969, none of the members are allowed to leave. I doubt the US would have invaded any of them if they'd broken that clause though.
