Three $0 defense spenders: 1) Costa Rica dissolved its army in 1948 after a short but bloody internal conflict, with the decision incorporated into the country’s constitution.; 2) In 1990, Panama followed suit, dismantling its army after the American invasion to remove the country’s military dictator, Manuel Noriega.; 3) NATO membership seems to be enough for Iceland as different member states take turns guarding their air space.
