On Sept 5/07, The Australia-United States Treaty on Defense Trade Cooperation was signed by Australian Prime Minister John Howard and US President George W. Bush. The USA and Canada have had a special agreement for several decades, designed to remove many defense export restrictions on US-Canadian industrial cooperation. In June 2007, Britain and the USA also agreed to a treaty framework.
The new agreements with Britain and Australia were not fully defined when signed, however, and full implementation is a long and complicated process. This article explains the issues with the current system, the intent of the treaty, and the steps involved on the way to finally implementing it in May 2013.
