The White House is facing criticism for social media posts about the US attacks on Iran that use what appear to be footage from popular Japanese animation and video games.

On March 5, it uploaded a video with the message "JUSTICE THE AMERICAN WAY" that mixed footage of attacks on Iran with scenes from the popular anime series Yu-Gi-Oh! and Dragon Ball.

An official Yu-Gi-Oh! social media account carried a comment on Wednesday denying the involvement of anyone associated with the manga or anime. It said permission was not granted for the use of its intellectual property.

The videos are being criticized for their offhand tone. The New York Times said they "reduce the war's carnage and upheaval to flippant, dystopian amusements."

The White House also posted an image and a video that appear to borrow footage from popular Nintendo video games.

The image includes the slogan "Make America Great Again" on a background apparently taken from the latest Pokemon video game.

The video combines images from US attacks on Iran with gameplay footage from the "Wii Sports" series. The 52-second clip, posted on Thursday, opens with a game start screen displaying the name of the military operation, "Operation Epic Fury." The scenes are intercut with footage of the US military attacking Iranian vessels and facilities.

The video is drawing online criticism, with one social media post saying, "war is not a game" and another claiming the video itself is a war crime.
