Costa Rica has not had an army for 64+ years

Costa Rica has not had a military since December 1, 1948.
"The money that was formerly spent on the military is now spent on education and universal health care and has had a tremendous effect on human development for the average Costa Rican."

I think that more countries should do this. I know it is an impossibility, but it seems to be working very well for Costa Rica.
