The majority of oversea intellects consider the punishment of Liu Xiao-po is appropriate. Only a small portion of anti-china activists like Taidu, Zhongdu, Jiangdu, HK democratic activists etc. are on Liu's side with intentional voices.
Liu's speech and intention on overthrow the Chinese government is apparent. Such crime (advocating to overthrow the government)if happened in the U.S., the punishment would be much harsher than that of the Chinese government.
The Western Countries are pushing a conspiratorial scheme namely: "boiling a flog with cool water". They want to plant seeds of dissidents into China's population expecting they bloom in the future so as to uptern China.
