Britain’s role in the recent machinations of the US empire has been central, despite going underreported and little criticized. Britain has a significant hand in the ongoing US war of aggression against Iran and their recent invasion of Venezuela. Britain’s empire and overseas bases, and associated intelligence and surveillance capabilities, are cornerstones of its contribution to these ongoing wars. Just as Britain’s colonial bases in occupied Cyprus served an intelligence and surveillance role in the Gaza genocide, so to did they help surveil Iran and prepare intelligence in preparation for US attacks, and are now being used as a staging post for those attacks. The ongoing UK-Mauritius Chagos Islands deal and subsequent US-UK rift over Diego Garcia’s use in the attack on Iran shows the potential for decolonial practice in international law and is a case that the US-UK Bases off Cyprus campaign can learn from.
