If I was him, I'd have included the multiple fire-bombings of German cities at the end of WW2 by Winston Churchill and Bomber Harris. If anyone needs to own up to war crimes, it's Britain.
But the USA also have been critical of Sri Lanka. This is the country that deliberately fried a hundred thousand Japanese civilians with one bomb, with the justification of ending the war quickly.
And Churchill's war crimes are a matter of documented history. Those of Sri Lanka are just allegations, made by a beaten enemy. The Tamil Tigers were responsible for horrendous atrocities over the years, against their own people, as well as the government, and it would be impossible to prevent instances of revenge taking place.
They also used civilians as a shield, right to the end, and must take most of the blame for the deaths of Tamil civilians at the end of the war.
I've got no sympathy whatsoever for the tossers.
Sri Lankan President Mahinda Rajapaksa has reacted defiantly to the UK's call for an inquiry into alleged human rights abuses, saying "people in glass houses shouldn't throw stones".
He was speaking on the second day of the Commonwealth summit in Sri Lanka.
UK premier David Cameron had urged Mr Rajapaksa to ensure an independent inquiry, or face a UN investigation.
The abuses are alleged to have been committed mainly against Tamils since the end of the war in 2009.
Pro-government commentators have pointed to alleged abuses under British colonial rule to suggest Britain has no moral right to criticise Sri Lanka.
And Mr Rajapaksa made an oblique reference to Bloody Sunday, when 13 civilians were shot dead in Northern Ireland by the British army in 1972.
Some inquiry reports took 40 years to emerge, he said, referring to an inquiry into the shootings which reported in 2010 and laid responsibility for the events on the army.
He also accused the Sri Lankan government's critics of ignoring deaths during the period of the civil war.
"Every day for the last 30 years people were dying... so we have stopped it," he said.
"We will take our time and we will investigate into 30 years of war," he added.
Mr Rajapaksa has said the end of the war has brought peace, stability and the chance of greater prosperity to Sri Lanka.
Basil Rajapaksa, President Rajapaksa's brother and a senior minister in his government, had already rejected Mr Cameron's call for an inquiry, saying it "definitely" would not be allowed to take place.
The government is carrying out its own investigation but denies civilians were killed in the last stages of the war when government troops routed Tamil Tiger rebels in their last stronghold.

Mr Cameron, speaking on Friday in the capital Colombo, ahead of the Commonwealth summit, said he had urged Sri Lanka's president to go further and faster over human rights issues and reconciliation.
In a meeting with President Rajapaksa, he called for Sri Lanka to ensure "credible, transparent and independent investigations into alleged war crimes" and said if this did not happen by March he would press the UN Human Rights Council to hold an international inquiry.
The prime minister met Mr Rajapaksa on Friday after a visit to the northern Jaffna region to see the situation facing the country's Tamil minority.
He said strong views had been expressed but the meeting with the president had been worthwhile.
Sri Lankan officials' reaction to Mr Cameron's intervention has been furious, the BBC's Charles Haviland reports from Colombo.
The government has been repeating the rhetoric it has used since defeating the Tamil Tiger militants, our correspondent reports.
It is grateful to allies such as Pakistan and now Australia which give it credit for ending the war, and resents the UK, Canada, the US and others which criticise the way it did it - as did a UN-mandated panel which estimated the offensive killed 40,000 civilians, he adds.
'Right track'
Mr Cameron said of his meeting with Mr Rajapaksa: "I accept it takes time but I think what matters is getting on the right pathway, getting on the right track, because it's only through generosity, through reconciling people that you can make the most of this country.
"So, a frank meeting - of course not everything I said was accepted but I sense that they do want to make progress on these issues and it will help frankly by having international pressure in order to make sure that that happens."
Earlier, the UK leader met Sri Lankan cricketer Muttiah Muralitharan, a Tamil who works for reconciliation in his country.
