Seems to me that with saying anyone that doesn't go along with sanctions against Russia and Iran will also have US sanctions imposed on them and now with saying we should go back to the G8 format (which discounts the value of the democrat/Eurocrat "Russia, Russia, Russia" meme to zero) is his way of getting to his goal through a back door.
He'll make enough trouble for them that they'll be anxious to have less US control of anything in Europe starting with our permanent leadership roles within NATO which often take precedence over what the Eurocrats want..
JMHo
NATO stopped being the entity it was designed for long ago. Heck they just announced if Gaza attacked Israel they would NOT assist Israel because they aren’t a member....yet look at what we flood into Ukraine who isn’t either!
