The violence initiated by Yasser Arafat after his rejection of the Clinton-brokered peace deal was a worst-case scenario not only for those whose lives were now in danger in the Middle East but for Western negotiators and supporters of the peace process. It presented them with the nightmarish lesson that there is risk in negotiating; the failure of talks could mean years of war.

But this year’s failed talks pushed by Secretary of State John Kerry are demonstrating another way peace talks aren’t necessarily risk-free: the deterioration of relations between the PA and Israel. As the talks collapsed, Mahmoud Abbas went ahead with a unity deal with Hamas, which immediately raised questions about Israeli support and the sharing of intel with the previously Hamas-less government. And today Haaretz sheds light on the nasty business of the blame game, with a letter apparently written by Israel’s national security advisor to Western governments:

Attached to the letter, a copy of which has been obtained by Haaretz, is a 65-page document that chief Palestinian negotiator Saeb Erekat submitted to Palestinian President Mahmoud Abbas on March 9, three weeks before Israel was to release the final batch of Palestinian prisoners. In it, Erekat proposed a strategy for the PA during the final month of negotiations and after April 29, when the talks were originally scheduled to end before their premature collapse.

Erekat recommended applying to join various international conventions, informing the U.S. and Europe that the Palestinians wouldn’t extend the talks beyond April 29, demanding that Israel nevertheless release the final batch of prisoners, intensifying efforts to reconcile with Hamas to thwart what he termed an Israeli effort to sever the West Bank from Gaza politically, and various other diplomatic and public relations moves.

Over the past month, the PA has implemented most of Erekat’s recommendations. This, Cohen wrote in his letter, shows that even while the Palestinians were talking with Washington about the possibility of extending the peace talks, they were actually planning to blow them up, and had been planning to do so even before Abbas met with U.S. President Barack Obama on March 17. …

The document also shows that the Palestinians planned in advance to take unilateral steps in defiance of the commitment they made when the talks were launched in July 2013, he wrote.

The Israeli leadership’s decision to share that information was apparently made in response to the Palestinians’ attempt to blame Israel for the stalled negotiations. Leaking the letter to the press is also a good way to push back on the craven and self-discrediting efforts by Martin Indyk’s team to blame Israel in order to settle old scores. The blame game is, of course, far better than an intifada, which was Arafat’s answer to an offer of peace and mutual coexistence. But that doesn’t make it any less unpleasant.

It’s worth pointing out that the letter isn’t necessarily the smoking gun it appears to be; the Palestinians will no doubt claim that it was a fall-back list of options in case talks fell apart, which they always do. But that’s also a self-fulfilling prophecy, since the talks usually end with the Palestinians walking away.

Yet that’s really a side issue here. The larger implications of this have to do with the fact that Kerry’s obsessive and badly mismanaged drive for a deal that was not in the offing has consequences for just about everyone but Kerry. He and Indyk can turn their attention elsewhere as they hit the Israelis with a sneering parting shot, but their gamble has left the Israelis and Palestinians worse off and scrambling to pick up the pieces.

The fact that there is some risk in negotiations doesn’t mean such negotiations should never take place: it would be courting disaster if a negotiated solution were permanently taken off the table. But neither should peace talks be seen as all upside, the way Western diplomats have tended to believe. Nor should they always focus on grand final-status deals just because an arrogant secretary of state like Kerry wants his Nobel. Kerry and Indyk may be used to others cleaning up their messes for them, but it’s clear both Israel and the Palestinians are getting tired of it.
