7. One fun thing...

Diplomacy, or what passes for it, seems to happen on twitter these days.

US President Donald Trump blew up any consensus that might have emerged from the weekend's G7 meeting with a couple of angry tweets from Air Force One on Saturday morning in response to Canadian Prime Minister Justin Trudeau pushing back against Trump in a news conference.

"PM Justin Trudeau of Canada acted so meek and mild during our @G7 meetings only to give a news conference after I left saying that, 'US Tariffs were kind of insulting' and he 'will not be pushed around.' Very dishonest & weak. Our Tariffs are in response to his of 270% on dairy!"

Impulsive and petulant doesn't even start to cover it.

But Trump wasn't the only one using Twitter to fire a few shots.

This picture for the ages of German Chancellor Angela Merkel and her mates laying down the law to an arms-crossed Trump said more than any diplomatic cable could. The fact the picture was taken by Germany's official photographer, Jesco Denzel, and was released on Twitter by Merkel's press liaison person, Steffen Seibert only makes it more powerful.
