To add on to your point, you publicly support allies while having private conversations counseling them on prudent courses of action. They don’t listen to you if you call them out publicly, which is usually a sign that privately articulated red lines have been crossed. I’m sure Biden is pressing them privately to have a more measured response, and is likely to have more traction than if he was publicly trashing them.
Just like you don’t use all available sanctions out of the gate with an adversarial state, to leave room to negotiate and leave some channels open. Diplomacy is more nuanced than “saying it like it is” all the time.
I was going to say, I think voters have long been able to mislead themselves, lol. Eating the onion is/was a real thing.
