In December 1971, at the outset of “the Troubles” in Northern Ireland, Edward Heath’s then home secretary, Reginald Maudling, announced that the British government had managed to ensure that an “acceptable level of violence” had been achieved. Taken out of context, these awkward words—which essentially meant that civil war had been averted—were thrown back at the government many times thereafter. They were said to denote a poverty of ambition, implying that the people of Northern Ireland would just have to deal with terrorism and civil strife as part of everyday life. The current conflagration across the Middle East brings to mind Maudling’s words once more. It seems that the wider the flames spread, the less the west seems exercised by the details.

The one exception to this is the Israel-Palestine conflict, for which there has historically been a lower threshold of tolerance for “acceptable levels of violence” than elsewhere in the Middle East. This is a phenomenon for which many explanations have been offered. Some point out that there is a double standard when it comes to criticism of Israel, especially when compared with the acts of brutal authoritarian regimes such as that in Syria. The death toll in Syria’s civil war is reported to have been 3,000 in July alone. Another 1,300 civilians were killed in Iraq in the same month.

Others have said that Israel occupies a special place in the western psyche because it has the support of the most powerful western states and because, as a democracy, it should be held to a higher standard of behaviour—hence the greater emphasis on the question of “proportionality” in the present Gaza war. Both suggestions have an element of truth to them.

Yet there is perhaps a third explanation for the despair that has greeted the latest gut-wrenching violence in Gaza. It is that, of all the conflicts engulfing the Middle East, the one in Israel-Palestine is seen as having a solution that is both conceivable and possible to envisage for those on the outside looking in. While the “hand of history” has come and gone here on many occasions, several peace deals have been close in the past. Indeed, the latest war came after ten months of talks, led by the US secretary of state, John Kerry. These began in July 2013 and had aimed at a final status agreement by the middle of this year.

Kerry embarked on the process in the sincere belief that he could achieve success, and there have been fleeting glimpses of progress. The contrast with Syria—or even with Iraq, the default response for which has become a shrug of the shoulders—is worth noting.
