Putin could’ve agreed to that framework and even signed on officially. It is what Trump was working so hard to achieve. It would’ve given Trump the leverage he needed to force Zelensky and Europe to the table.
I don’t doubt Trump is a master of seeing the deal-middle.
Getting people to see it is another thing.
Being free to act is another.
In this case, it’s like the time-share salesman (Trump) who wants your wife (Zelensky’s EU controllers) at the table too, so you both agree to buy.
That said, if you use or create all the leverage you can and they won’t agree, there is no deal at this time.
