Gamble on the Jordan.

The article presents information on terrorists attacks in Israel. The Israelis appeared anxious to avoid casualties, and by Jordanian account only six civilians were killed in the action. Actions against Syria have been tried before, but the mountainous terrain along the Syrian frontier makes them difficult. That is the simplest explanation. But it raises the question of whether Israel's leaders would risk the international consequences for so little gain, especially when similar raids into Jordan in 1965 obviously had little effect.
