While the West’s enemies become ever more unrestrained in the barbaric nature of their attacks, Islamist militants are increasingly pursuing tactics aimed at limiting what the West can do in its own defense. As a recent case in Britain has demonstrated, jihadists and their supporters are more than happy to fabricate the most outlandish allegations in an often successful attempt to hinder the fight against them. This is the kind of thing that Israel has been having to deal with for decades, and at some point other Western states need to comprehend that they are all up against the same enemy, one which is willing to employ the same underhanded tactics against all of us.

In May 2004, British troops became embroiled in a three-hour gun battle with insurgents of the Mahdi Army at Al Amara, Iraq. Following the battle it was alleged that British soldiers tortured, executed, and then mutilated the bodies of twenty Iraqi detainees. These accusations have dragged on for a decade now and in response the UK government commissioned the al-Sweady Inquiry, an investigation which has cost the British taxpayer almost $49 million, with the accusers having been able to claim financial assistance from the British state to fund their case against it.

And what did the tribunal discover? The al-Sweady Inquiry has stated unequivocally that the allegations made against the British soldiers are “without foundation,” and that those making these accusations had given evidence that was “unprincipled in the extreme” and “wholly without regard for the truth.”

So after years of investigation, and tens of millions in public money spent (much of it having been used to assist those bringing claims against the British army), the soldiers have at long last had their names cleared while the jihadi militants have been exposed as liars. Hardly surprising; it’s simply delusional to imagine that those who are so unprincipled as to use terrorism to achieve their aims would suddenly become upstanding and honest witnesses once stood before a war-crimes investigation. What these people are, however, is mendacious and calculating, and regardless of what al-Sweady may have concluded, by using public money to advance these outrageous allegations the jihadists have won by hijacking the West’s liberalism and respect for the rule of law for their own advantage.

Quite apart from the tremendous financial cost that this investigation and many more like it have carried, the decade that these allegations circulated for have been an outstanding public-relations victory for the insurgents. The media–large parts of which were eager to see Western forces fail in Iraq and Afghanistan–were all too ready to believe the stories spun by the militants and to think the worst of our soldiers. By parroting these lies ad nauseam, the Western media assisted the militants in undermining public morale at home, eroding belief in the rightness of the cause we were fighting for and convincing many that intervention overseas is rarely a defensible or admirable undertaking. In Europe particularly, these tales provide the recruiting fodder that radicalizes young Muslims into believing that their host societies are evil and that they too must join the war against the West. If nothing else, the constant fear of these damaging war crimes allegations persuade Western governments and militaries to be still more restrained in the tactics that they feel able to use in the increasingly muted attempt to counter our enemies.

This of course is the war that Israel has been fighting for years, ever since its creation in fact. Most recently there have been feverish blood libels about the IDF harvesting Palestinian organs, of summary executions during the 2010 flotilla incident, and of a supposed massacre and mass graves in Jenin during the Second Intifada. With all of these accusations Israel is obliged to investigate the conduct of its military, and so it does. That was what was so outrageous about the UN’s Goldstone investigation and indeed the subsequent attempt to have a Goldstone II following the war in Gaza this summer. Such international inquiries are only supposed to be mandated where a state has failed to adequately investigate itself first–but in Israel’s case the international community simply steps in and puts on its own investigation regardless, usually with the conclusion having been written at the outset.

Israel, like Britain and America, does undertake costly and time-consuming investigations where there are allegations of war crimes. But as we have seen so many times before, within hours the international media will have beamed the most tarnishing accusations against Israel around the world several times over. Months later when investigators have established the allegations as baseless, no one is listening anymore and the damage is done.

The debacle of the al-Sweady Inquiry has naturally caused some outrage in Britain, and so one hopes that some lessons will have been learned. But if observers have been reminded that jihadists are readily prepared to use war crimes accusations as a second front in the war against the West, they should also recognize the same tactic when they see it being deployed against Israel. The problem is that while many of them may now realize that the Islamists their armies encounter are unreasonable fanatics, they are equally convinced that the Islamists Israel faces have a legitimate grievance and a just cause.
