I believe that Britain should not intervene in Hong Kong. If we do, then China might spark war with us. If non nuclear warfare devastated us, then how would you expect a nuclear warfare to go. I wouldnt take the risk. If Hong Kong are suffering and Britain denies, just ask all the other trading partners such as Austrailia, Japan or USA? i strongly believe that britain should not intervene in the situation because it will create a rivalry between Britain and China (and we have a really good trading system). I wouldn't say this but it is a possibility. WWIII? Human extinction? it's a very very smal chance, but it is an idea.
