If this were to happen, the US government would respond with severe condemnation and likely take action. It would call on other world governments to take a collective stand against Hong Kong’s decision and the violation of human rights. The US could impose sanctions on Hong Kong or other entities with ties. It is possible the US government could involve the United Nations or other international bodies to take a unified action against Hong Kong. It may also provide material support and resources to the individuals affected by the decision.
