Amos J. Hochstein is an American businessman, diplomat, and former lobbyist. Wikipedia
He currently has the job of mediator between Lebanon and Israel.
Here is the problem, according to Lebanese law, it is illegal for passport holders having Israeli stamps or have any visit to Israel be able to enter Lebanon and any person who tries gets arrested or denied entry per this Wikipedia article:
Admission and transit is refused to nationals of Israel. Travelers who hold passports that contain stamps, visas, or seals for Israel will be denied entry into Lebanon and may be subject to arrest or detention.
So how is this guy able to enter both countries without scrutiny, do these rules not apply to diplomats?
