Let those rascals harm and kill Hong Kong at their hands and feet ( if these extremists are Hong Kong residents and inhouse foreign expats ).
Let them collect the pieces and fix up the pieces ( toiling in the sun and rain and typhoons ).
If they need up to 23 more years from today to fix Hong Kong up nicely again ( if ever Hong Kong can be the same again ) , allow it to happen.
If US foul Congress has a very discriminatory bloody Bill approved to oppress and threaten Hong Kong and its population, then China ( if not Hong Kong ) ought to cut-off all treaties tied to the SAR of China. The USA is already applying strangle-holding arms against China's neck that even commercial enterprises like Huawei, ZTE and several others of China are not spared. So, what is Hong Kong without US foodstuffs, goods, hundreds more pieces of many that the latter (USA) need to sell and barter ? US folks and companies in Hong Kong are the first to suffer a US's choking scenario of atrocities quite often seen elsewhere in this world !
It is the time to manifest our great power handling this kind of seperatism, we believe our country can solve it quite on our own ,no need of other hypocritical countries to interfere in and give any so called guidance, we can do it ourselves.
In essence US is a country that cannot be trusted. For nations which hold the USD as reserve currency, one day US may tax them or even force them to concede substantial concessions to the US or to do US' dirty works. One fine day US will make USD currency holders pay for holding its currency.
It is up to countries to first design their own mechanism to be free from what US has created over the last 30 years to enslave the world. Not that it is good to reinvent certain mechanisms but to be held hostage by US perpetually is not what freedom is all about in the first place. This will also embolden US only to commit more crimes only. US' Congress does not have the mandate to act beyond its national borders yet it has done it so frequent as if this world is its slave. It bombs any country that it wants and it tells lies without having to be accountable - all these are not similarly available to a common person in this world. Yet US has the guts to profess that it maintains people's liberty.
Its time to articulate US' actions and behavior globally and put US back to its own position. Designing international dissemination of information is vital. China has to manage its international image while control US'. Think if China or China and one or two others can turn the tables on US, wouldn't that be fantastic? For now US isn't alone and China should pick from the global platform.
