Personally ... I think the tariffs were a stupid idea. They went against the advice of all experts.
I don't get the whole "Free trade agreement" thing. I mean, how many hundreds of pages is it?
You want "free trade" between countries? I can do that in a single page.
How difficult is it to say that trade from those countries will be treated the same way as interstate commerce? LOL
(too bad that isn't what is going to happen)
And, of course, there's the fact that unilaterally pulling out of deals - whether personal or between nations - NEVER sits well with the other parties involved.
