ICJ ruled on the validity of Colombia’s claims to islands off the coast of Nicaragua. It’s ironic because the islands are four times the distance from Columbia than Nicaragua, but they ruled Columbia’s territorial claims include all the way out to the islands. It’s almost 500 miles of water claims that are now included in Columbia’s territory. Meanwhile, Costa Rica is in the corner with the least amount of water territory in the Caribbean.
