Speaker. in view of Nassers bellicose threats. his relentless arms buildup. and his continued espionage and sabotage activities against Israel. I believe that it is most reasonable indeed. for Israel leaders to view with serious concern. his efforts to establish a fifth column within Israel itself. I have long maintained that the solution to the Arab refugee problem must be a part of a general peace plan for the Middle East. The problem is not one which exists in a vacuum. nor is it an isolated issue nettling the relations of otherwise friendly governments. And its resolution. like the arms problem and water dispute. can only be worked out within the context of the larger problem.
