U.S. President Donald Trump is reportedly frustrated and sleepless over his inability to swiftly resolve the ongoing conflict in Ukraine.

Axar.az reports that the Wall Street Journal revealed that Trump shared these concerns last week during a private conversation with sponsors at his golf club in Florida.

“Trump admitted that negotiating with Russian President Vladimir Putin has been extremely difficult. Another major challenge has been finding solutions to the conflicts in the Middle East. Trump said resolving international disputes turned out to be much harder than he initially thought,” the article stated.
