"Better red than dead," again, huh?
For starters, even your own source article states that only half of that number died during the Reagan administration. These wars long predated him. That, of course, assumes he didn't pull the original number out of his ass.
Apparently, the fact that most inhabitants of those nations are quite happy with how things turned out doesn't mean much to you.
I'm sure fewer people would have died fighting if Central America had just surrendered to the Soviet puppets. Then, as with Iraq, all the killing would have taken place at night, behind walls, and comfortably out of sight of the leftists who have worshipped such regimes since before I was born.
