You are still welcome to refute anything Austin has said with support, but it seems you have none.

From your link:
SNIP Now, there are a mix of 4,500 Marines, soldiers and airmen securing the Hamid Karzai International Airport to the north of the city and assisting in processing U.S. citizens and Afghans with Special Immigrant Visas for military flights out of the country.

The White Hose authorized up to 6,000 U.S. troops to support Operation Allied Rescue – the mission to evacuate Afghans who worked with the U.S. – and the parallel non-combatant evacuation operation that has yet to be named publicly. SNIP

So you failed to mention we upped the troops from the inadequate 2500 left under Trump and authorized up to 6000 for the evacuation. This is why he said there were insufficient troops at 2500. You either misunderstood or omitted it.

So you make unsupported statements, can't refute Austin - though it should be easy, and you make ad hominum attacks (a logical fallacy) while you accuse others of logical fallacies.

Insisting that a claim is true simply because a valid authority

Did you notice that I didn't *insist* it's true? That's why it isn't a logical fallacy also. I showed it to you and invited you to show otherwise.

You also do cavalier mocking and derision, possibly because of lack of substance. You aren't dumb Dope, you can do better.
