On July 8th of this year, Joe Biden said all of these things in front of the press:

Q Is a Taliban takeover of Afghanistan now inevitable?

THE PRESIDENT: No, it is not.

Q Why?

THE PRESIDENT: Because you — the Afghan troops have 300,000 well-equipped — as well-equipped as any army in the world — and an air force against something like 75,000 Taliban. It is not inevitable.
