This was a tidy summary but not my own... debate continues about who came up with it first and its been around forever it seems. 

It seems, it could well fit Trump especially when it comes to the "process" of governance. 

He campaigned from stage 1 which he gave the fashionable title Political Outsider. Plus lots of puffing about how He knew all about EVERYTHING.  But now, is the hardwork of governing from the inside. Puffing doesn't get it done. Bigly coming soon!

So again, dropping by to see the Pope is the distraction that he will hide behind while the real stuff of the Malta meeting has him flat footed probably wearing a tiny ear piece. 

this link may shed more light on the real issues in the Italy trip... http://www.consilium.europa.eu/en/meetings/european-council/2017/02/03-informal-meeting/

Trump  presents as fact something he'd like to see happen. And then dares people to disappoint him. "Looking forward to meeting with the Pope" said beside Italy PM  was one of those.
