Smallpox has been eliminated from the human population, but two nations – the US and Russia – insist on keeping the pathogen in cold storage. They claim their purpose is to develop defences against possible biological weapons attack, but most experts in the field consider this to be nonsense. While raising concerns about each other’s possession of the disease, they have worked together to bludgeon the other members of the World Health Organisation, which have pressed them to destroy their stocks.

In 2001 the New York Times reported that, without either Congressional oversight or a declaration to the Biological Weapons Convention, “the Pentagon has built a germ factory that could make enough lethal microbes to wipe out entire cities”. The Pentagon claimed the purpose was defensive but, developed in contravention of international law, it didn’t look good. The Bush government also sought to destroy the Biological Weapons Convention as an effective instrument by scuttling negotiations over the verification protocol required to make it work.

Looming over all this is the great unmentionable: the cover the US provides for Israel’s weapons of mass destruction. It’s not just that Israel – which refuses to ratify the Chemical Weapons Convention – has used white phosphorus as a weapon in Gaza (when deployed against people, phosphorus meets the convention’s definition of “any chemical which through its chemical action on life processes can cause death, temporary incapacitation or permanent harm”).

It’s also that, as the Washington Post points out: “Syria’s chemical weapons stockpile results from a never-acknowledged gentleman’s agreement in the Middle East that as long as Israel had nuclear weapons, Syria’s pursuit of chemical weapons would not attract much public acknowledgement or criticism.” Israel has developed its nuclear arsenal in defiance of the non-proliferation treaty, and the US supports it in defiance of its own law, which forbids the disbursement of aid to a country with unauthorised weapons of mass destruction.

As for the norms of international law, let’s remind ourselves where the US stands. It remains outside the jurisdiction of the International Criminal Court, after declaring its citizens immune from prosecution. The crime of aggression it committed in Iraq – defined by the Nuremberg tribunal as “the supreme international crime” – goes not just unpunished but also unmentioned by anyone in government. The same applies to most of the subsidiary war crimes US troops committed during the invasion and occupation. Guantánamo Bay raises a finger to any notions of justice between nations.

None of this is to exonerate Bashar al-Assad’s government – or its opponents – of a long series of hideous crimes, including the use of chemical weapons. Nor is it to suggest that there is an easy answer to the horrors in Syria.

But Obama’s failure to be honest about his nation’s record of destroying international norms and undermining international law, his myth-making about the role of the US in world affairs, and his one-sided interventions in the Middle East, all render the crisis in Syria even harder to resolve. Until there is some candour about past crimes and current injustices, until there is an effort to address the inequalities over which the US presides, everything it attempts – even if it doesn’t involve guns and bombs – will stoke the cynicism and anger the president says he wants to quench.

During his first inauguration speech Barack Obama promised to “set aside childish things”. We all knew what he meant. He hasn’t done it.
