Alec Baldwin may have said that he won’t be impersonating President Trump for much longer, but the actor returned to “Saturday Night Live” this weekend to play the commander in chief.

The episode kicked off with a sketch that looked to the future. The year is 2018, aliens have invaded Earth and embattled U.S. troops look to the president for inspiration — you know, the typical big action-flick premise.

“We’ve lost limbs, we’ve lost lives, but we will not lose the United States of America,” says a general, played by Kenan Thompson. “But first, your commander in chief wants to say a word.”

In rolls Trump, played by Baldwin, pouty mouth and all. But he keeps getting off track as he tries to rev up the troops and offer a strategy to fight back.

“Hello, yes, what a beautiful day. Who here loves Trump? I know this guy here loves Trump,” Baldwin says, pointing to a charred body.

Then he lays it out: “Here’s the deal: We are going to beat these aliens because we have got the best military, but we don’t win anymore. And the aliens are laughing at us. They’re killing us, and they’re laughing at us.”

“We know the aliens are killing us, sir,” the general says. “They have the most advanced weaponized technology we have ever seen. What should we do?”

Trump answers: “Okay, here’s what we are going to do. We are going to bring coal back, okay?”

The state of California has been vaporized, the general says. “So, then, I won the popular vote?” Baldwin-as-Trump responds.

The general adds that this “highly advanced” alien species is from the planet Zorblat-9, but Trump signals skepticism about that, adding, “I’ve actually heard Zorblat-9 is very beautiful, very fantastic.”

A horrified soldier chimes in, “Oh, my God. Does he have business ties on Zorblat-9?”

Throughout the sketch, the general tries to impress upon the president the dire situation the country is in; most of the land is controlled by the aliens, with just a small portion remaining under U.S. control. But Baldwin-as-Trump talks about how NBC has been “very unfair to me,” and he bungles the Pledge of Allegiance.

In the sketch, Trump also puts forward a theory — not gleaned from FBI or CIA intelligence, but one he has heard from Alex Jones of Infowars (“You know he’s legit because he’s always taking off his shirt, okay?” Trump says in the sketch).

“I actually heard the aliens are already here. They have been hiding in this country for hundreds of years,” Baldwin-as-Trump says. “It’s a fact. They’re shape-shifters. They look like regular people, but they’re aliens. Look, there’s one right there,” he adds, pointing out black troops.

Finally, the aliens arrive at the scene: “Humans! Resistance is futile. Take me to your leader.”

Trump pauses, then points to the general. “It’s him. He’s the president.”

Later on in SNL, Baldwin briefly shows up as the president during a prerecorded short about Ivanka Trump.

It’s unclear how much longer Baldwin will continue the Donald Trump impersonation. “The maliciousness of this White House has people very worried, which is why I’m not going to do it much longer by the way, the impersonation,” Baldwin told “Extra” last week. “I don’t know how much more people can take it, you know.”
