NEW YORK, November 24. /TASS/. US President-elect Donald Trump is extremely worried about the escalation of the conflict in Ukraine and where it is going, said Representatives Mike Waltz, the incoming national security adviser.

Trump is "incredibly concerned" about the escalation that is taking place and "where it’s all going," he said on Fox News.

"We need to bring this to a responsible end," he added. "We need to restore deterrence, restore peace, and get ahead of this escalation ladder rather than responding to it."

Putin said on November 21 that Russia fired its newest Oreshnik hypersonic intermediate-range ballistic missile with a non-nuclear warhead at a Ukrainian defense industry facility in Dnepr. According to the president, it was a response to strikes into Russian territory with UK and UK weapons. The Russian leader said Russia is developing intermediate-range and shorter-range missiles in connection with US plans to produce and deploy similar weapons in Europe and the Asia-Pacific.
