Problem: Direct U.S. military involvement ended on 15 August 1973 as a result of the Case-Church Amendment passed by the U.S. Congress. The fall of Saigon by the North Vietnamese Army in April 1975 marked the end of the war, and North and South Vietnam were reunified the following year. The war exacted a huge human cost in terms of fatalities (see Vietnam War casualties). Estimates of the number of Vietnamese soldiers and civilians killed vary from 966,000 to 3.8 million. Some 275,000-310,000 Khmer people, 20,000-62,000 Lao people, and 58,220 U.S. service members also died in the conflict, and a further 1,626 remain missing in action. The Sino-Soviet split re-emerged following the lull during the Vietnam War and ties between the DRV and its Cambodian allies in the GRUNK, the newly-formed Democratic Kampuchea begun almost immediately in a series of border raids by the Khmer Rouge and erupted into the Cambodian-Vietnamese War, with Peoples Liberation Army directly intervening in the Sino-Vietnamese War. The end of the war and resumption of the Third Indochina War would precipitate the Vietnamese boat people and the bigger Indochina refugee crisis, which saw an estimated 250,000 people perish at sea.

Problem: The representatives of the Provisional Russian Administration in Principality of Bulgaria, who sympathised with the struggle, were reprimanded by the Russian Emperor in person. These were the decisive reasons for Its failure, parallel with reasons of internal and organizational character. Typical for the uprising was the scale participation of volunteers - Bulgarians of all parts of the country. Some figures as an illustration: 100 volunteers from Sofia, 27 from Tirnovo, 65 from Pazardzhik, 19 from Troyan, 31 from Pleven, 74 from Orhanye, 129 from the Plovdiv district, 17 from Provadia, 30 from Eastern Rumelia and others. A large number of insurgents and leaders of different parts of Macedonia also participated in the uprising. After the Upspring some 30,000 refugees fled to Bulgaria. The failure of the uprising lead to the attention of the Bulgarian political and strategic leaders to liberation of the other parts of the Bulgarian territories and to other main strategic objective - unification of the Principality of Bulgaria and Eastern Roumelia, the later being under Sultans power, but still having a large autonomy. Macedonia and Thrace should have to wait.
