I guess you missed my wikipedia link when Jordan took them in. Here's more:
" Most of its targets were Arab politicians, rivals, and activists they felt were soft on the Israeli issue, but Jews, as well as political representatives of Western nations were also targets, especially those involved in the peace process in the Middle East. Notably, ANO enacted a drastically violent policy towards its own members – executing some 600 members and their families in 1987"
Another Wiki link regarding Abu Nidal undoubtably as much adored as Biden and Obama. Keep telling me how we should feel sorry for the children as their parents keep supporting Hamas.
