Israels attacks on the Palestinian terrorist groups key staff and infrastructure has seriously reduced the ability to launch successful terrorist attacks. Hamas has been humiliated by Israeli raids into Gaza, where superior Israeli training and tactics keep their casualties low while accomplishing their mission (capturing terrorist suspects or destroying terrorist workshops or supplies). As a result, Hamas, and other Palestinian terrorist groups, are turning more to foreign terrorist organizations. In particular, Hizbollah, which operates in Lebanon with the support of Syria and Iran, has been found providing increasing amounts of assistance. Israel, and the United States, has warned Syria and Iran to back off in supporting terrorism. Syria and Iran deny any involvement. The inability of Hamas to strike back quickly for the killing of their leader has put the Palestinian terrorists under pressure to at least spread rumors of really big future attacks. But the problem, as in any war, is one of logistics. The Israelis have been effectively attacking terrorist logistics for over a year. The losses of key technicians, organizers and supplies has made it increasingly difficult to launch terrorist attacks. There is no shortage of volunteers to be the bombers, but the critical bottleneck is the resources needed to get the bomber trained, and then moved through Israeli checkpoints to a target in Israeli occupied areas.
