> it's not a legal text that you get to angle shoot out of

LOL yes we can and we will. I can state this confidently because the entire agreement is exactly that. A bunch of terms with definitions too vague to matter.

If Trump wants to be an unreliable ally again, then everybody knows he will do so anyway. It'll be based more on what kind of breakfast he had than whether the EU sticks to the terms or not.

No, you don't understand. It is literally not a legal text - but an semi-formal agreement. Both sides are free to do as they see fit (or not), but in the end it's essentially a list of tribute that the EU will pay to Trump, and he gets to decide if it fits the standards of what is expected.
