Activists declare: Britain’s foreign policy has failed
Thursday 16th November 2017
BRITAIN’S foreign policy has failed — we needs a change of direction and an anti-war government, campaigners declared yesterday.
Despite government denial over its military interventions, Britain is involved in seven theatres of war, Stop the War said, adding that the by-products have been an increased threat of terror attacks and a rise in racism.
The meeting heard how women have not been liberated 16 years after the war on Afghanistan despite it being one of the declared aims of the British and US invasion.
And, as a result of the war, 36 per cent of the population are on the poverty line and only 27 per cent have access to safe drinking water.
And British arms sales are being put above human rights with a 500 per cent increase in trade of missiles and other weapons with the Saudi regime since its bombing of Yemen began over two years ago.
The briefing aims to provide information for trade unionists, students and activists to win the arguments against the government’s drive for wars and argues for a “radically different foreign policy.”
