It has been four years since the U.S. withdrew from Afghanistan, ending a 20-year foreign entanglement and leaving the fates of hundreds of thousands of people in the hands of the Taliban.

For House Republican lawmakers who served in the Armed Forces, in the Middle East in particular, the frustration and angst is still raw.

"I thought the withdrawal was the worst thing I've ever seen from any president in my lifetime. It was the most bungled operation I've seen," Rep. Don Bacon, R-Neb., told Fox News Digital.
