Cops of the World by Phil Ochs captures the zeitgeist again | Brief letters

US imperialism | Trump’s actions in Venezuela | Roosevelt’s big stick | Tony Blair Institute | Citizen’s arrest | Fifa peace prize | Triumph of evil Phil Ochs, who died 50 years ago this year, released a song called Cops of the World in 1966. Suffused with Ochs’ sardonic wit, it ridiculed US imperialism and disregard for international law. It captured the zeitgeist then, and sadly is even more relevant now. Mike Pender Cardiff • The G8 was a discussion forum for leaders of major industrialised nations (Canada, France, Germany, Italy, Japan, Russia, UK, US), until it became the G7 in 2014, after Russia annexed Crimea. After Donald Trump’s acts against Venezuela and threats against Denmark and Greenland, is it time for a G6? Denis Jackson Glasgow
