The emergence of the convicted spy Jonathan Pollard as a bargaining chip in Israeli-Palestinian peace negotiations is a lamentable sign of America’s desperation to keep both sides talking. Peace between Israelis and Palestinians can be achieved only if they want it for themselves, something that is very much in doubt right now.

An Obama administration proposal to free Mr. Pollard, an American intelligence analyst serving a life sentence after spying for Israel, as a political gesture toward Prime Minister Benjamin Netanyahu of Israel is a bad idea and would do nothing to advance progress on the core issues of a peace deal.

After nine months of talks, there is no sign of progress on any of these issues. In addition, Israel has refused to follow through on a promise made in July to free 104 prisoners in four groups in exchange for a Palestinian vow to refrain from pressing the statehood issue in United Nations agencies and the International Criminal Court.

Mr. Netanyahu and other Israelis have long demanded the release Mr. Pollard, who has spent nearly 30 years in prison; the Americans have long resisted. He is up for parole next year and said to be ailing, so it might conceivably be worth releasing him early if it could help Mr. Netanyahu take the leap on a truly big decision, like a final peace agreement. But releasing him as a small-bore tactical step to persuade Israel to do what it had already promised? That is not a price worth paying.
