“We will continue to try to impress upon them that we can’t do anything and everything forever,” said one senior administration official, referring to Ukraine’s leaders. The official, who spoke on the condition of anonymity to discuss sensitive diplomatic matters, added that it was the administration’s “very strong view” that it will be hard to keep getting the same level of security and economic assistance from Congress.
“'As long as it takes’ pertains to the amount of conflict,” the official added. “It doesn’t pertain to the amount of assistance.”
