Sihanouk, who by now had tired of the political squabbling, dissolved the assembly in September 1949, but opted to rule by decree for the next two years before general elections were held, which the Democrats won. In October 1951, Thanh returned to Cambodia and was received by 100,000 supporters, a spectacle which Sihanouk saw as an affront to his regal authority. Thanh disappeared six months later, presumably to join the Khmer Issarak. Sihanouk ordered the Democrat-led government to arrest Thanh but was ignored. Subsequently, civil demonstrations against the monarchy and the French broke out in the countryside, alarming Sihanouk, who began to suspect that the Democrats were complicit. In June 1952 Sihanouk dismissed the Democrat nominee Huy Kanthoul and made himself prime minister. A few days later, Sihanouk privately confided in exasperation to the US chargé d'affaires, Thomas Gardiner Corcoran, that parliamentary democracy was unsuitable for Cambodia.
