I immediately called for two things. The NRA to organize an armed protest, and to persona-non-grata all attackers not American citizens, and to arrest those that are and don't have DI (diplomatic immunity). What happened is the Turks are thugs, and when they heard/saw pro PKK "protestors" they consider "terrorists" they wanted to make an example of them. I'm guessing it was also a distraction technique for Erdogan to…
I think we should be treating this as an attack by the government of Turkey against United States civilians. They are no longer an ally. I suspect that we unfortunately have more to lose than Turkey by ending our friendly relationship, but so be it. Staying in a dysfunctional relationship isn't good for either country.
I would like to see the bodyguards prosecuted, but at the same time I expect they are operating under some kind of threat worse than what the United States legal system could potentially do to them. Maybe their wives and daughters will be arrested if they don't attack certain protesters? They may be in a no-win situation. The best thing may be to just get them to leave and not return, even if that offends our sense of justice.
