Trudeau did adopt some of Trump’s lingo when addressing him –by his forename, as you point out–, using “big” several times and referring to some treaty they negotiated as a “deal”. He also slowed down, as if talking to someone with impaired understanding. Finally, Trudeau delivered this gem:

Now, it’s not in my habit to agree with the Wall Street Journal, but Donald, they point out that, even though you’re a very smart guy, this is a very dumb thing to do.

It was brilliant; out in plain sight for anyone with mild linguistic skills yet too subtle for the Trump base to grasp any of it.

To my knowledge, intelligence gathering is one of the capabilities for which Ukraine and, indeed, all non-US members of NATO depend on the United States the most, and one which they can less readily ramp up than the production of military hardware and materiel. This latest move is, perhaps, an even bigger blow to a fair and durable peace than the recent suspension of US military aid.
