The left must fight imperialism in the name of patriotism. Barring a revolutionary and highly unlikely transformation of American mass culture, any political party that wishes to win majority support will have to demonstrate its commitment to the defence of the country. The Bush administration has used the accusation of weakness in security policy to undermine its opponents, and then used this advantage to pursue reckless strategies that have themselves drastically weakened the US. The left needs to heed Bacevich and draw up a tough, realistic and convincing alternative. It will also have to demonstrate its identification with the respectable aspects of military culture. The Bush administration and the US establishment in general may have grossly mismanaged the threats facing us, but the threats are real, and some at least may well need at some stage to be addressed by military force. And any effective military force also requires the backing of a distinctive military ethic embracing loyalty, discipline and a capacity for both sacrifice and ruthlessness.
