Faced with the stripping of their powers, Wu Sangui, later joined by Geng Zhongming and by Shang Kexi's son Shang Zhixin, felt they had no choice but to revolt. The ensuing Revolt of the Three Feudatories lasted for eight years. Wu attempted, ultimately in vain, to fire the embers of south China Ming loyalty by restoring Ming customs, ordering that the resented queues be cut, and declaring himself emperor of a new dynasty. At the peak of the rebels' fortunes, they extended their control as far north as the Yangtze River, nearly establishing a divided China. Wu then hesitated to go further north, not being able to coordinate strategy with his allies, and Kangxi was able to unify his forces for a counterattack led by a new generation of Manchu generals. By 1681, the Qing government had established control over a ravaged southern China which took several decades to recover. Manchu Generals and Bannermen were initially put to shame by the better performance of the Han Chinese Green Standard Army, who fought better than them against the rebels and this was noted by Kangxi, leading him to task Generals Sun Sike, Wang Jinbao, and Zhao Liangdong to lead Green Standard Soldiers to crush the rebels. The Qing thought that Han Chinese were superior at battling other Han people and so used the Green Standard Army as the dominant and majority army in crushing the rebels instead of Bannermen. Similarly, in northwestern China against Wang Fuchen, the Qing used Han Chinese Green Standard Army soldiers and Han Chinese Generals such as Zhang Liangdong, Wang Jinbao, and Zhang Yong as the primary military forces. This choice was due to the rocky terrain, which favoured infantry troops over cavalry, to the desire to keep Bannermen in the reserves, and, again, to the belief that Han troops were better at fighting other Han people. These Han generals achieved victory over the rebels. Also due to the mountainous terrain, Sichuan and southern Shaanxi were also retaken by the Han Chinese Green Standard Army under Wang Jinbao and Zhao Liangdong in 1680, with Manchus only participating in dealing with logistics and provisions. 400,000 Green Standard Army soldiers and 150,000 Bannermen served on the Qing side during the war. 213 Han Chinese Banner companies, and 527 companies of Mongol and Manchu Banners were mobilized by the Qing during the revolt. 400,000 Green Standard Army soldiers were used against the Three Feudatories besides 200,000 Bannermen.

A cover story in BusinessWeek magazine claims that economists mostly failed to predict the worst international economic crisis since the Great Depression of the 1930s. The Wharton School of the University of Pennsylvania's online business journal examines why economists failed to predict a major global financial crisis. Popular articles published in the mass media have led the general public to believe that the majority of economists have failed in their obligation to predict the financial crisis. For example, an article in the New York Times informs that economist Nouriel Roubini warned of such crisis as early as September 2006, and the article goes on to state that the profession of economics is bad at predicting recessions. According to The Guardian, Roubini was ridiculed for predicting a collapse of the housing market and worldwide recession, while The New York Times labelled him "Dr. Doom".
Which school at University of Pennsylvania examined in their online business journal why economists failed to predict the crisis?
A: The Wharton School

In mid-June 1940, when international attention was focused on the German invasion of France, Soviet NKVD troops raided border posts in Lithuania, Estonia and Latvia. State administrations were liquidated and replaced by Soviet cadres, in which 34,250 Latvians, 75,000 Lithuanians and almost 60,000 Estonians were deported or killed. Elections were held with single pro-Soviet candidates listed for many positions, with resulting peoples assemblies immediately requesting admission into the USSR, which was granted by the Soviet Union. The USSR annexed the whole of Lithuania, including the Scheschupe area, which was to be given to Germany.
