The overthrow was engineered in Moscow; we monitored the transmissions, the orders, each and every step of the way ... while Carter ordered "no action."
The same happened to a couple countries in southern Africa.
The same occurred with regard to Grenada, but President Reagan immediately ordered "action." The same occurred with regard to Panama, but President Bush I ordered "action."
President Carter learned nothing, because the lesson is mostly that we must be prepared to act, and it is expensive to be so, yet that costs less than when we are not.
Unfortunately, we currently are not prepared; thank the Clinton Legacy. For as much as the buildup may seem, we are woefully without spare parts for maintenance, nor do we have the depots we need to support maintenance in the event of an emergency.
We, if anything, are desparate for a four-fold increase in the number of suits for our forces to wear in the event of a chemical or biological attack.
Looking at it in hindsight, we now come to see that those "political prisoners" were actually fundamentalist muslims, and terrorists. Funny how that seems like a much better idea now.
