Question: When did the troops of the country blamed for the stagnation and failure of the Tripartite discussion leave the country that receives the most U.S. foreign aid?

medical knowledge had stagnated during the middle ages. the most authoritative account at the time came from the medical faculty in paris in a report to the king of france that blamed the heavens, in the form of a conjunction of three planets in 1345 that caused a "great pestilence in the air". this report became the first and most widely circulated of a series of plague tracts that sought to give advice to sufferers. that the plague was caused by bad air became the most widely accepted theory. today, this is known as the miasma theory. the word 'plague' had no special significance at this time, and only the recurrence of outbreaks during the middle ages gave it the name that has become the medical term. <SEP> 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. <SEP> Top 25 Recipient Countries of U.S. Foreign Aid FY 2013 Reported in $US millions, Obligations Country Economic and Military Assistance FY 2013, $US millions Aid received per person recipient FY2013, $US Economic Assistance FY 2013, $US millions Military Assistance FY2013, $US millions Afghanistan 4533.51 148 2653.93 1879.58 Israel * 2961.04 367 17.81 2943.23 Egypt 1566.24 19 330.6 1235.6 Jordan 1211.83 188 879.64 332.19 West Bank / Gaza 1007.73 370 Ethiopia 686.53 7 685.19 1.34 South Sudan 618.74 55 598.79 19.96 Malawi 571.18 35 570.91 0.27 Uganda 541.93 14 538.3 3.62 South Africa 526.19 10 523.86 2.32 Nigeria 518.84 509.41 9.43 Russia 465.16 445.07 20.08 Iraq 444.81 13 382.7 62.11 Tanzania 430.66 9 427.82 2.84 Mexico 419.94 348.72 71.21 Congo (Kinshasa) 379.24 6 366.73 12.52 Haiti 378.77 37 377.04 1.73 Lebanon 376.41 84 286.03 90.38 Somalia 367.18 35 188 179.18 Zambia 310.8 22 310.26 0.54 Sudan (former) * 290.05 8 290.05 <SEP> By the end of May, drafts were formally presented. 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. 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 USSR proposed to consider that a political turn towards Germany by the Baltic states would constitute an "indirect aggression" towards the Soviet Union. 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. <SEP> at the same time, british, french, and soviet negotiators scheduled three-party talks on military matters to occur in moscow in august 1939, aiming to define what the agreement would specify should be the reaction of the three powers to a german attack. the tripartite military talks, started in mid-august, hit a sticking point regarding the passage of soviet troops through poland if germans attacked, and the parties waited as british and french officials overseas pressured polish officials to agree to such terms. polish officials refused to allow soviet troops into polish territory if germany attacked; as polish foreign minister józef beck pointed out, they feared that once the red army entered their territories, it might never leave.
