TV prankster Sacha Baron Cohen has fired a return salvo in his war of words with Sarah Palin.

The comedian drew ire from the former Alaska governor by posing as a military veteran to draw Palin into an ambush interview for his new show, “Who is America?”

Palin took to Facebook to air her rage at Cohen in a lengthy screed on Tuesday.

“I join a long list of American public personalities who have fallen victim to the evil, exploitive, sick ‘humor’ of the British ‘comedian’ Sacha Baron Cohen, enabled and sponsored by CBS/Showtime,” she wrote.

Now Cohen has answered her — sort of.

He tweeted an in-character reply under the pseudonym Billy Wayne Ruddick Jr., PhD — the protagonist he portrays in the new show.

“Here’s the truth @SarahPalinUSA #MAGA #buildthewall #boycottsashacohen,” @BillyWRuddick tweeted Thursday, along with an image of a letter made to look as though it was produced on a typewriter.

“…[I]t was I that interviewed you,” the missive reads in part. “I did NOT say I was a War Vet. I was in the service — not military, but United Parcel, and I only fought for my country once — when I shot a Mexican who came onto my property.”

He takes swipes at the one-time vice presidential hopeful for questioning President Barack Obama’s nativity, and even addresses the letter to “Vice-President Palin” though she and running mate John McCain lost to Obama and Joe Biden in the 2008 presidential election.

“You used to hunt the most dangerous animals in the country, like wolves and people on welfare. So why hunt a fine citizen journalist like myself?” the letter states. “I DEMAND an APOLOGY.”

Palin caught wind of the phony missive Thursday, calling it in a Facebook post “another list of unfunny lies, this time typewritten for all to see; a pathetic attempt to punk not just my daughter and me again, but now the public.”
