Why No Anti-Boycott Law for Israel?

Alana Goodman writes deprecatingly in regard to an anti-boycott bill in the Knesset:

This has to be the worst idea for Israel’s public image yet...It sounds like it would simply be impossible to enforce.  But worse, it could even be counterproductive.

but America already has one in place:

During the mid-1970's the United States adopted two laws that seek to counteract the participation of U.S. citizens in other nation's economic boycotts or embargoes. These "antiboycott" laws are the 1977 amendments to the Export Administration Act (EAA) and the Ribicoff Amendment to the 1976 Tax Reform Act (TRA). While these laws share a common purpose, there are distinctions in their administration.

Objectives:
The antiboycott laws were adopted to encourage, and in specified cases, require U.S. firms to refuse to participate in foreign boycotts that the United States does not sanction. They have the effect of preventing U.S. firms from being used to implement foreign policies of other nations which run counter to U.S. policy.

Primary Impact:
The Arab League boycott of Israel is the principal foreign economic boycott that U.S. companies must be concerned with today. The antiboycott laws, however, apply to all boycotts imposed by foreign countries that are unsanctioned by the United States.

so why can't Israel?
