Mr. President. for the United States. there is an assured backing up of all these ideas. plus the willingness to put up practically what is being put up now in the way of economic aid for the area. which is about $500 million a year. Finally. for the Soviet Union. to use a curbstone phrase. it is time to "put up or shut up." In short. the Soviet Union should show a willingness to contribute at least to something as elementary as the settlement of the Arab refugee problem. to which it has never contributed a ruble. This is the opportunity to put the problem up to the Soviet Union. to see whether the Soviets will do anything to help or will continue to concentrate solely on propaganda. I think that events have now boiled to the point where the opportunity for the United States is great.
