it doesn't directly rebut the post, but the poster you are responding to is emphasizing that costa rica is only able to maintain their military-free status by allying with one of the most powerful militaries in the world. it's probably a good thing that not every country in the world needs to maintain a full-scale military, but this only works if you have a powerful ally whom you can trust to defend you. the fact that costa rica is able to exist without a military doesn't imply that the US could also disband their military.
