40 years ago, on 2 April 1982, war broke out between Argentina and the United Kingdom over the Falkland Islands. The ruling classes of the two countries hypocritically justified the conflict with phrases about national freedoms, the interests of the Falklanders, etc. But in reality, as Ted Grant explains in this pamphlet published on May 1982, and which we reproduce here, this war was reactionary on both sides. Exposing the cowardice and the half-baked formulas of the labour bureaucracy and of some so-called Marxists, Ted analyses the reason behind the outbreak of the war and its consequences, and puts forward an internationalist Marxist position on the conflict.
