US President Donald Trump will not tolerate Zelensky's escalating rhetoric.

Axar.az reports that US National Security Advisor Mike Waltz stated this on Fox News.

"I think the frustration has really stemmed just in the last week from this bizarre pushback and escalation of rhetoric over a presentation of what we see as an absolute opportunity – and that’s to have the United States invest in Ukrainian infrastructure, to have them grow both their minerals, their natural resources, their oil and gas. We believe the American taxpayer deserves to recoup much of their investment. All of that’s an opportunity for Ukraine. They need to see that for what it is. And instead, we had this kind of escalating rhetoric and pushback, and the President [Trump – ed.] is not going to tolerate it."
