Here’s David Bier:
The Hong Kong Safe Harbor Act would directly support protesters by telling them that they can risk their lives in Hong Kong knowing that they have a backup plan in case they are targeted. The Chinese party is already clearly concerned about this type of offer, denouncing the United Kingdom’s similar proposal to allow up to 3 million Hong Kongers to enter and work in the UK and claim UK citizenship.
This proposal would also benefit the United States by providing it with talented new Americans committed to freedom and democracy (a commitment too few U.S.-born Americans share). The program would support U.S. diplomatic efforts to defend democracy and freedom in Hong Kong, and it would embolden freedom fighters the world over.
