Mahmoud Abbas, the president of the Palestinian Authority, said something cryptic last Friday, shortly after the Israelis began their latest round of attacks on the Gaza Strip. Condemning Hamas's conditions for accepting a ceasefire as "exaggerated and unnecessary," he offered his condolences "to the families of the martyrs in Gaza who are fuel to those who trade in war. I oppose these traders, on both sides."
What could he mean by that? Surely he was not suggesting Prime Minister Benjamin Netanyahu of Israel and the leaders of Hamas, the Islamist organization that has effective control of the Gaza Strip, have a common interest in perpetuating the current bloodbath for at least a little while longer.
Yes, he was suggesting exactly that, and he was quite right. This is the third "Gaza War" since late 2008 -- they come around more often than soccer World Cups -- and each one has followed the same pattern. Some Israelis are kidnapped and/or killed, Israel makes mass arrests of Hamas cadres in the West Bank and launches air and missile strikes on the Gaza Strip, Hamas lets the missiles fly, and away we go again.
A few wrinkles are different this time. The kidnapping and murder of three young Israeli hitch-hikers in the West Bank, probably by Palestinians who had links with Hamas (although it denies responsibility), was followed by the torture and murder of a young Palestinian, probably by Israeli vigilantes.
The ceasefire signed after the last round in 2012 was already being violated by both sides for some months before the real shooting started a week ago. And, most importantly, Hamas had achieved a political reconciliation of sorts with Mahmoud Abbas's rival organization that rules the West Bank as the Palestinian Authority. But although every turn of the wheel is a little bit different, the pattern remains the same.
So why would Prime Minister Netanyahu be willing to launch Israel's third war against the Gaza Strip in eight years? Because the nature of his political alliances with other parties on the Israeli right, and especially with the settler lobby, means he could not make a peace deal the Palestinians would accept even if he wanted to (which he probably doesn't).
That's why he was instrumental in sabotaging the Oslo Accords, the theoretical basis for a peaceful two-state solution to the Israeli-Palestinian conflict, during his first term as prime minister in 1996-99. Back in power in the past five years, his primary excuse for not moving on negotiations has been that Mahmoud Abbas could not deliver peace because he controlled only the West Bank, while the intransigent Hamas ruled the Gaza Strip.
Then Abbas stitched together a compromise that brought Hamas back into a unity government three months ago, and Netanyahu claimed he could not be expected to negotiate with a government that included the "terrorists" of Hamas. So is he now trying to destroy Hamas so Abbas can rule unhindered over all the Palestinian territories and become a suitable partner for peace? Of course not.
Netanyahu knows, on the evidence of the previous two wars, that Hamas can be battered into temporary quiescence but not destroyed. He also probably realizes if he did manage to destroy Hamas, its place would be taken by a less corrupt and much more extreme Islamist outfit that might really hurt Israel. He is just doing this, with no expectation of victory, because Israeli public opinion demands it.
Hamas's motive for wanting a little war are more obvious and urgent: It has lost almost all its sources of funding. Iran stopped funding its budget to the tune of $20 million per month when Hamas sided with the Sunni rebels in the Syrian civil war.
Egypt stopped helping it after last year's military coup against Mohamed Morsi's Muslim Brotherhood government, and closed the tunnels under the border through which the Gaza Strip received most of its imported goods. Those imports were Hamas's main source of tax revenue. Hamas is broke, and if it stays broke its control over the Strip will weaken.
Whereas a war with Israel will rally the local Palestinians to its support, and if enough of them are killed Egypt and the Gulf states may feel compelled to give Hamas financial aid. So the only real question is how many dead Palestinians will satisfy both Netanyahu's need to look tough and Hamas's need to rebuild popular support at home and get financial help from abroad.
On past performance, the magic number is between 100 and 1,000 dead: around 1,200 Palestinians were killed in the 2008-9 war, and 174 in 2012. After that -- assuming only a handful of Israelis have been killed, which is guaranteed by the fact Israeli air and missiles strikes are a hundred times more efficient at killing than Hamas's pathetic rockets -- a ceasefire becomes possible.
We have already crossed the lower threshold of that range of Palestinian deaths in the current mini-war, so a ceasefire is theoretically possible now, but both sides will probably press on for at least another few days. Then the ceasefire will be agreed, and both sides will start thinking about the next round, only a few years from now. But the dead will stay dead.
