That led to the 1979 peace treaty between Egypt and Israel that has lasted to the present day. Sadat and Begin were awarded the Nobel Peace Prize in 1978 for their efforts in reaching the agreement that they made.
As to the other answers:

Similarly, the increase of tensions with the Soviet Union over the Olympics would not be an example of a success.
The federal law regarding cleaning up hazardous waste would be a success item, but one of <u>domestic</u> policy, not foreign policy.
