Zelenskyy decided to send Putin a letter in his own handwriting to let him know he was still in the game.

Putin opened the letter which appeared to contain a single line of coded message.

Putin was baffled, so he sent the message to Lukashenko, and his aides had no idea either, so they sent it to the KGB.

No one could solve it at the KGB either, so a double agent sent it to the CIA, then the NSA. They also didn’t know what it meant.

Finally, the CIA director sent the message to The Australian Military for help. Within a few seconds, they called back with this message:

"Tell that dumb wanker Putin he’s holding the message upside down."
