There is a great irony in the collapse of US-backed Afghan forces and the success of the Taliban.
While the US officially focused on pulling US troops out of Afghanistan, what we really pulled out was the air power that supported not only US troops, but more importantly also Afghan soldiers.
The irony is that the US Air Force hated the Afghan campaign because the war lacked the kind of targets the US Air Force was designed to strike.
The United States has the most sophisticated and highest tech air force in the world, bar none. The F-22 and F-35, the two flagship fighter bomber and air superiority aircraft, lead the world in stealth and overall capability.
