In mid-June, the main Tripartite negotiations started. The discussion was focused on potential guarantees to central and east European countries should a German aggression arise. The USSR proposed to consider that a political turn towards Germany by the Baltic states would constitute an "indirect aggression" towards the Soviet Union. Britain opposed such proposals, because they feared the Soviets' proposed language could justify a Soviet intervention in Finland and the Baltic states, or push those countries to seek closer relations with Germany. The discussion about a definition of "indirect aggression" became one of the sticking points between the parties, and by mid-July, the tripartite political negotiations effectively stalled, while the parties agreed to start negotiations on a military agreement, which the Soviets insisted must be entered into simultaneously with any political agreement. The origins of al-Qaeda can be traced to the Soviet war in Afghanistan (December 1979 – February 1989). The United States, United Kingdom, Saudi Arabia, Pakistan, and the People's Republic of China supported the Islamist Afghan mujahadeen guerillas against the military forces of the Soviet Union and the Democratic Republic of Afghanistan. A small number of "Afghan Arab" volunteers joined the fight against the Soviets, including Osama bin Laden, but there is no evidence they received any external assistance. In May 1996 the group World Islamic Front for Jihad Against Jews and Crusaders (WIFJAJC), sponsored by bin Laden (and later re-formed as al-Qaeda), started forming a large base of operations in Afghanistan, where the Islamist extremist regime of the Taliban had seized power earlier in the year. In February 1998, Osama bin Laden signed a fatwā, as head of al-Qaeda, declaring war on the West and Israel, later in May of that same year al-Qaeda released a video declaring war on the U.S. and the West.
