Aid to Khmer Rouge, aid to the Contra's, aid to South Africa (though eventually forced to cut ties), aid to Suharto, aid to the FMLN, illegal invasion of Grenada, illegal bombing of Libya, etc, etc. The Reagan Doctrine is a collection of skeletons.
Unfortunately, there is little to admire about his fiscal agenda either. Reagan's policy was one of deliberately reducing the standard of living of Americans; deindustrializing the nation and shifted skilled workers to burger-flipping jobs, and brutal cuts to services. Meanwhile, his "Future Tradings Act" led to the hyper-speculation of "derivatives," making the situation even more chaotic. His "just say no" was a pathetic failure, and his supporters seeming forget his presidency marked what remains the highest homicide rate in American history.
This sums it up better than I ever could though:
