Where is Our Dunkirk?

Why haven't we heard about any resignations or firings at the Pentagon and State Department over this shameful, inexcusable, nightmarish debacle in Afghanistan?

This is from National Review: "Secretary of Defense Lloyd Austin said that the U.S. will continue to evacuate all the Americans 'they can' from Afghanistan, although the U.S. is currently unable to 'go out and collect large numbers of people' from outside the Kabul airport.
'It’s obvious we’re not close to where we want to be,' Austin said at a press conference at the Pentagon. 'We’re gonna get everyone that we can possibly evacuate evacuated, and I’ll do that as long as we possibly can, until the clock runs out, or we run out of capability.'
Austin admitted that U.S. capabilities to venture outside the airport are already limited, however. 'I don’t have the capability to go out and extend operations currently into Kabul,' explained the defense secretary. There are currently up to 15,000 Americans still in Afghanistan, U.S. officials have estimated."

Yet in 1940, over 338,000 British and French soldiers were rescued from Dunkirk! Yet we can't manage to evacuate 15,000 Americans from Afghanistan?
