Yeah --------- I'm not so worried about that sort of stuff. His folksy way of talking about things is okay with me, as you quote. I'm not one of those people who think Biden is particularly senile: I think this talk is ageist and partisan. Not that I think he should run again: enough is enough.
But we are seeing a pattern of tough talk immediately negated by all his staff, and I am very interested in that. Maybe it is senility! But maybe it's a sort of diplomatic dance. Kim Jun Il does that all the time. Hitler did it all the time. Threatening, then pulling back at once. Threatening again, then pulling back. Hitler meant the threats; so far, Kim never has. So what is going on with Biden, I wonder. I sure don't want to get into war with China. Or Russia. On the other hand, if they are sure we won't go to war, they'll walk all over us. I think "I'm senile and I have the Bomb!" may be a calculated warning.
