Anyone rattles a country's stabilities deem dangerous. You are emotional and refuse to look at other side of the coin. You don't want to look into bombings of civilian buses and residences by Chinese domestic terrorists throughout China. You don't look into how criminals behave against victims in China. Oh, you will just sing anti-China whenever you grab a piece of data, but never analyze what the data contain and represent.
Stop tearing a country apart because your fervent disbeliefs of its land sovereignty. Tibet is part of China. It does not allow secession. Just like India's fervent beliefs of Kasmir as part of its sovereign, it will do whatever it takes to hold on to it.
Furthermore, you are sure the pictures are not propagandas for some political agenda? It is easy for you sing and support any seperation of the State from your end; however, Chinese people die, not you.
