President Joe Biden was absolutely correct regarding Afghanistan's history of disunity. It has never been a unified country. Any outsider seeking to conquer Afghanistan has encountered tribal groups, war lords - disparate fighters uniting only to expel foreign invaders. Mr. Biden, unlike George W. Bush, who began America's longest war, knows history and, no doubt, availed himself of the academics that are the real experts of what has happened, for centuries, in the region. His wife is a professor.

And then there was President Trump, who wanted to meet the Taliban for face-to-face negotiations at Camp David! House Minority Leader Kevin McCarthy, who viciously attacked President Biden over the exit from Afghanistan, should remember that. But, despite the events of January 6th, Mr. Trump's best bud should apologize for his own ignorance.

Hopefully the continued exit will be without further incident.
