Israel has increasingly isolated itself from the world with its hard-line policies on West Bank settlements, the Gaza embargo and other issues. This week, it unwisely set itself further apart with a decision to withhold cooperation from a United Nations Human Rights Council review of its human rights practices.

When the first reviews began in 2008, every country in the world, including the United States and Israel, participated in the process, which is supposed to examine each country’s human rights record every four years. But when the council met on Tuesday in Geneva for its second review cycle, Israel was a no-show.

In May, Israel said it planned to stop participating because the council was a “political tool” for those who wanted to “bash and demonize” Israel. The council, whose 47 members are elected by the United Nations General Assembly, is clearly not without faults. More than half of the resolutions passed by the council since it started work in 2006 have focused on Israel and its treatment of Palestinians, and Israel is the only country that is a standing item on the agenda for the council’s biannual meetings.

The council hasn’t always been an effective human rights champion. But its record, including naming human rights rapporteurs for Iran and Sudan and supporting gay and lesbian rights, has improved since President Obama, reversing policy of the George W. Bush administration, had the United States join the council in 2009.

Human rights reviews are an important tool for judging all countries by universal standards and nudging them to make positive changes. By opting out, Israel shows not only an unwillingness to undergo the same scrutiny as all other countries, but it deprives itself of an opportunity to defend against abuse charges. The decision could also undermine the entire review process by providing an excuse for states with terrible human rights records — like North Korea, Iran and Zimbabwe — to withdraw as well. It certainly will make it harder for Washington to argue for reviews when an ally rejects the process.

If the government of Prime Minister Benjamin Netanyahu hoped to avoid criticism by this move, it failed. Fortunately, there is still a chance to make the right decision. In an extraordinary move, the council agreed to give Israel until November to reverse course. Any new governing coalition that emerges from Israel’s recent elections should realize that there’s a cost to standing apart.
