Hong Kong is the jurisdiction of China. Hong Kong residents don’t have the right to govern themselves.
He is saying that Israel, probably especially Jerusalem, should not have the right to govern itself. In effect, Jews living in Israel would have to rely upon the UN to protect it.

In particular, Hong Kong doesn’t have its own army, it depends on China for its defense needs (meaning that China’s army is, for any practical purpose, keeping a gun trained on them). For Israel, that situation would mean being just a step from destruction.
or worse, it should be the bailiwick of slammie countries that surround it
