That's not the interesting metric, though. In fact it is destined for nothing but un-informativity.

What is interesting is, among all military members who are trained by foreign governments, how many of the US-trained ones go on to stage coups vs those trained by other nations?

Along these lines, there is a very disturbing pattern.

Other countries that have the same policy (most notably France, Britain, and, historically, Prussia) have the same kind of record, and it still seems like a pittance, percentagewise.

The US has a lot of (eroding) institutional infrastructure to reduce the chances of it happening at home, and throughout the republic some have expressed an interest or tried, most notably during the US civil war when about a third of the West Point graduate generals who fought were on the Confederate side. The the coup plot in 1933 the very general the plotters wanted to recruit blocked it.
