FuLL HisTORy Of PaSHtUn KiNg's: Within three weeks of the Soviet invasion of Afghanistan the cabinet secretary, Sir Robert Armstrong, was negotiating how to channel covert military aid towards the "Islamic resistance" that was fighting the Russians. Details of how swiftly clandestine weapons routes were opened up to aid the mujahideen emerge from secret cabinet documents released to the National Archives today under the 30-year rule. The files show how extensive military and diplomatic efforts – co-ordinated with western allies – were made to defeat the USSR and the lengths to which Thatcher went to discourage participation in the 1980 Olympics. Shortly after KGB special forces seized control of Kabul on 27 December 1979, the foreign secretary, Lord Carrington, expressed the view: "The Russians are resorting to the big lie by saying that they intervened at the invitation of Afghan authorities … we should take every opportunity to make them uncomfortable and bring home to them the consequences of their actions." In mid-January Armstrong sent a "secret, personal" note to the prime minister on a meeting in Paris between senior US, French, German and British officials.
