Depends on how you look at it. The deal she made is never going to get ratified by the EU member states, but placated Trump enough to lower his stupid tariffs to acceptable levels. I think she 100% knew the deal she agreed with him was never going in effect and she just wanted to buy time, which so far has worked.
It makes a lot of sense to buy time for a variety of reasons. She took a hit to her image with this “deal” but she effectively accomplished all the goals she had going into those discussions. But from afar it looks like she was played.
It’s published in the local newspaper, but my brilliant wife puts it in a colour coded excel sheet and hangs it on the fridge, and gives our elderly neighbors copies.
