CACKLE DIPLOMACY: Roger Kimball: Kamala invades Poland.

You can tell that the Biden administration is getting serious. They have unleashed their ultimate weapon, cackle diplomacy. The warhead is nicknamed Harris, and it is now in Poland cackling away, endeavoring to assemble the high-level Pierogis before Russia flattens Kyiv or Putin decides to go nuclear — and by “go nuclear,” alas, I mean “go nuclear.”

Some observers say that sending Kamala Harris on this mission will give her a chance to “burnish” her foreign policy credentials. Cynical folks — and I would include myself in that group — think it is just another emission of fog by America’s first certifiably senile administration.

“Ukraine is a country in Europe,” Harris recently explained to universal hilarity, “it exists next to another country called Russia. Russia is a bigger country. Russia is a powerful country. Russia decided to invade a smaller country called Ukraine. So, basically, that’s wrong, and it goes against everything that we stand for.”

Did I mention that the hilarity was laced with feelings of appalled panic? This, after all, was the vice president of the United States.

Our leadership has gone from comically bad to tragically bad in the space of a month.
