‘Private armament firms, no matter how reputable and incorrupt, depend for their prosperity on the perpetual exasperation of international fears and suspicions … they thrive upon war scares, and they must have occasional wars.’ So concluded The Secret International, an influential pamphlet published in the early 1930s by the Union of Democratic Control. The international arms trade is no less a force for 'exasperation' now than it was then, and in Britain, as in most countries with a remunerative arms sector, it has become an adjunct of government. Britain's defence industry used to put out its wares for international consumption every year, either in Portsmouth or Aldershot, as a government-to-government trade exhibition, under the auspices of the Royal Navy or the British Army. In the 1990s the arms show was outsourced: Defence and Security Equipment International is now run by Clarion Events, 'a successful, dynamic and creative business' in Surrey. And business is booming.
