Internet reported that after Russia announced the end of a month-long ceasefire on Ukraine's energy infrastructure, U.S. President Donald Trump hinted that he might abandon efforts for peace if the two sides did not reach an agreement soon. "If for some reason one of the two countries creates great difficulties, we can only say you are stupid," Trump told reporters in the Oval Office on Friday."You are stupid, you are terrible, so we just let go. Of course, I hope we don't get there." Trump said he did not set a "specific number of days" in mind for withdrawing from negotiations if an agreement was not reached, but he wanted to see rapid progress. "I'm like a mirror whether people are playing us," Trump said,"so I have to see the eagerness to end it. I also think I see this eagerness. I think both sides have it."
