I get the feeling you've seen the early "trump patronising and trying to intimidate a visitor" clips, but not the "Macron addresses Congress" speech. Trump used the "holding hands" manoeuvre on Theresa as well, she practically giggled like a schoolgirl. Angela was too tough for him and he wouldn't look at her or shake her hand. He like subs. He doesn't like leaders.
No "Yo, Blair" for Macron.
