But macron said he'd do it.

Since when do we measure based on what some politicians say they'll do. I mean just look at what Trump says all day long.

I recently saw some stats (unfortunately can't find it) about the percentage of election promises that are actually being tackled at all by the winning party for many different countries and it was real depressing across the board.

You mean, about the bases? He cannot do it (and I am doubtful he’d actually say that; it’d be a diplomatic faux pas at a time when he needs consensus). What he said repeatedly is that Europe should be less reliant on the US.
