The terms of the hudna state that Israel is not to take action against the terrorists - against there is a "ticking time-bomb." This enables the terrorists to rearm and regroup until such time as they feel they can call off the hudna.
A senior IDF officer said that the PA's failure to deal with the terror infrastructures (as the Road Map requires) leads to the strengthening of the terror organizations. The freedom of travel in Gaza, he gave as an example, is enabling the organizations to train terrorists in firing rockets, prepare explosives, and transfer wanted terrorists from place to place. In addition, the Arabs continue to develop more advanced Kassam rockets - improving their range from 8 kilometers to 12. This will put Ashkelon and Prime Minister Sharon's Shikmim Farm into Kassam range.
