The radical rioters who stormed the Hong Kong Parliament in the past 12 hours (Youtube above) are reminiscent of the hopeful heroes who sat in Tiananmen Square in 1989. The world press are fooling themselves when they underestimate how Chinese military forces, responsible for Hong Kong, may react.
Damage to the Hong Kong Parliament provides a pretext for a paramilitary police and then a military crackdown on those (recorded on surveillance cameras and cell-phone trackers) who rioted. Perhaps a broader circle of democracy activists in Hong Kong will also be arrested.
The Beijing Government can suspend the convention that the Peoples Liberation Army (PLA) cannot interfere in Hong Kong's internal affairs. This is because the PLA has always had an underlying or active role in internal security for all regions of China.
The 6,000 PLA troops based in Hong Kong can quickly be reinforced with several brigades of armoured vehicles from the Mainland. The PLA's Hong Kong Garrison is under the direct leadership of China's Central Military Commission and under the administrative control of PLA's Southern Theater Command.
