John Howard’s decision to commit thousands of Australian troops to the invasion of Iraq 15 years ago ranks as one of the two great failures of Australian foreign policy since the Second World War.

The other is Menzies’ decision to send forces to Vietnam. Both cases represented an abysmal failure of Australian political leadership, driven by an unnecessary capitulation to strategically foolhardy decisions by the US administrations of the time.

Both decisions were taken without independent Australian analysis of the legitimacy of American war aims, the credibility of American military strategy to both win the war and secure the peace, as well as the long-term consequences for Australian national interests.

In the cynical world of politics it is important, just occasionally, to give credit where it is due. The commitments on carbon emissions announced on Wednesday by President Barack Obama of the US and President Xi Jinping of China, supported by the significant diplomacy of Secretary of State John Kerry, are both environmentally substantive and politically influential. Between them, these countries account for 44 per cent of global carbon emissions – a share that is still rising.
