Rescuing Arafat and his vermin from destruction by the Israelis was one of Pres. Reagan's biggest mistakes. He concentrated on defeating Communism, and probably considered this bunch of crazy Muslim ragheads not much of a threat to the world. He was right in dealing with Communism, but sadly underestimated the threat of Islam to the West. Had Arafat and Co. been killed, Hezbollah would not have come into being to terrorize the free world.
So true and the other mistake Reagan made was in not reversing Nixon's disasterous policy of allowing China access to the USA
