Europe alone is not responsible for helping Ukraine bring an end to its war with Russia, EU top diplomat Kaja Kallas warned Thursday.

Axar.az reports, citing Politico, that is particularly true when considering President Donald Trump’s pledge to halt the fighting, she said in an interview on the sidelines of the U.N. General Assembly.

“He was the one who promised to stop the killing,” Kallas said. “So it can’t be on us.”

There is no NATO without the U.S., said Kallas, the high representative for foreign affairs of the European Commission.

“America is the greatest ally in NATO. So if you talk about what NATO should do, that also means what America should do,” she said.

“Trump has been right,” Kallas said. “We have decreased our oil and gas purchases by 80 percent, which means that if everybody did what we do, there could be a bigger effect. We have done 19 packages of sanctions. If allies would mirror them, the war would be over sooner.”

“I understand what the Americans are saying — that they can’t put pressure on Russia because that would close the communication channels that they have with Russia, and they are the only ones mediating this,” she said.

But the positive gestures from the U.S. have not yielded results, she stressed.

“You are coming in good faith, you are offering all this so that [Russia] would come to the table, but they actually just escalate. … This goodwill is abused by Putin,” she said. “Now the question is, what do you do with this?”
