President Trump has posted what appears to be a text conversation between himself and NATO secretary general Mark Rutte.
"Congratulations and thank you for your decisive action on Iran," reads the effusive screenshot posted by Trump on Truth Social.
"That was truly extraordinary and something no one else dared to do."
The long message, full of praise for the president, says he has "made us all safer" and congratulates him for pushing NATO countries to up their defence commitments to 5% of GDP by 2035.
"Donald, you have driven us to a really really important moment for America and Europe, and the world," reads the screenshot.
"Europe is going to pay in a BIG way as they should, and it will be your win."
