I don't know. Time passes and things change. Financial institutions are weak spots of China, too, not just N. Korea. BDA of Macau was slapped with sanctions by U.S., whether China liked it or not at the time. U.S. can certainly target more Chinese banks.
Recently, some CFR types are advocating preemptive strikes to N. Korea, who are not Clintonoids. You would not imagine such a talk a few years ago. They are spouting only global free trade happy talk, and their theme has always been talk, negotiation, and appeasement.
A few, although the Krintinoids were obnoxiously omnipresent last week -- Madame Nothalfbright schtupping for her alleged ministerial services. She likes clinking champagne glasses with Chia Head -- that's her idea of diplomacy.
But obviously some CFR types know Chia Head is capable of screwing up SEA, which to a great degree equals their clientele.
Potentially they wonder how is it that the PLA cannot be convinced that they can still have a NK Sockpuppet to their liking, just not this Sockpuppet...
