@CR7isthebest: He was the leader of Panama who was taken by the Americans and thrown in a U.S. prison deep in the middle of the country. He was kept in prison until he died.
If you're a puppet working against your own country, you will eventually be betrayed and scapegoated by the puppeteer; it's inevitable.
Guillermo Endara, the president after Noriega's downfall, took many steps to distance Panama from Noriega's shadow. One of them was transforming the military forces into police forces (in order to purge Noriega loyalist from power), to the point that the military was abolished in 1994.
The issue with the "US did that" thing is that Endara was sworn president at a US base in Panama. He was refuged there after the military forces under Noriega attacked him. So, many would say "He did all under US influence."
Also surprising are some of the countries not included here, like St. Kitts and Nevis & Antigua and Barbuda.
Panama: It was a puppet state of the US, led by a general, so militaries aren't exactly a good memory for Panama people and like Costa Rica they don't really need an army. Everyone needs Panama to be let in peace, because everyone needs to use the canal. Their only potential threat would be Colombia if they wanted to take back Panama, but Colombia surprisingly doesn't want a war with the US, which is what annexing Panama would mean...
I was really surprised at Panama. I was also sure Grenada had a military. Didn't Clint Eastwood and a rag tag band of marines invade there. I was sure they met with some military resistance.
But that was in the 80's, no military since then.
And yes, yes, I know I should have read the subtitle, but one doesn't expect the subtitle to contradict the title.
