HBO Just Clapped Back at Donald Trump for Using a 'Game of Thrones' Reference to Announce New Sanctions on Iran

President Donald Trump on Friday tweeted a Game of Thrones-inspired meme of himself declaring new sanctions against Iran, and HBO isn't happy about it.

The image, emblazoned with "SANCTIONS ARE COMING NOVEMBER 5," is a play on "Winter is Coming," setting the stage for the final battle between the living and the dead in HBO's hit series. Trump's poster also copied Game of Thrones' signature font style.

A few minutes later, the White House retweeted Trump's message along with a dark announcement of its own:

"The United States has launched a campaign of economic pressure to deny the regime the funds it needs to advance its bloody agenda!"

In a statement to The Hollywood Reporter, HBO said it does not approve of its show's brand being used for political purposes.

"We were not aware of this messaging and would prefer our trademark not be misappropriated for political purposes."

HBO also tweeted: "How do you say copyright infringement in Dothraki?"

Must be a field day over there.

Reactions on Twitter were priceless.

J.K. Rowling nailed it.

Scott Dworkin was at a loss for words.

Sanctions really aren't something to gloat about.

This is what happens when 'rock bottom' rears its head and says, "hold my beer."

Like, this took work; real effort. Our tax dollars are hard at work.

Naturally, Twitterers fired back with Robert Mueller memes.

And spoofs.

Others questioned whether Trump has ever watched Game of Thrones, but given its complex plot and hour-plus-long episodes, probably not.

But what if he does?

Guesses abound.

There are parallels.

Scratch one item off the parallels list.

Secretary of State Mike Pompeo announced on Friday that all of the sanctions that were lifted as part of the 2015 Iran Nuclear Deal will be reimposed and will take effect on Monday, November 5 - the day before the critical midterm elections.
