For the last 20 years, Costa Rica's been making the kind of policy stances that used to pretty reliably get Latin American countries invaded by the Marines:

2. very pro organized labor
3. leftist economics
4. constant criticism of the US's policies by the Costa Rican foreign office
Anyone who has not a nuke is in deep trouble, because there are no neutral tiles on the board that is the great game.
