US officials described the hours of talks in Berlin as positive and said Trump in his call would seek to push forward the deal.
The US officials warned Ukraine must accept the deal, which they said would provide security guarantees in line with NATO’s Article Five – which calls an attack on one ally an attack on all.
“The basis of that agreement is basically to have really, really strong guarantees – Article Five-like – also a very, very strong deterrence” in the size of Ukraine’s military, a US official said on condition of anonymity.
“Those guarantees will not be on the table forever. Those guarantees are on the table right now if there’s a conclusion that’s reached in a good way,” he said.
