I find it interesting that it seems that those countries whose leaders were honest with their people are doing so much better than those who didn't. Because that allowed their people to understand and take steps to protect themselves. And speaking only for my own country, there was no panic at all. Much fear, followed by weary resignation, but no panic.
Keep in mind that "panic" for the Trumpkin* meant panic in the stock market. He doesn't give one rat's ass for the average American.
