President Donald Trump said that he is not hopeful for a peace agreement in the short term after a phone call yesterday wtih his Russian counterpart and that they might have to just "keep fighting" until they're unable to go on,

U.S. President Donald Trump sidestepped questions on June 5 as to when he can be expected to impose additional sanctions on Russia, as the Kremlin continues to reject a ceasefire in Ukraine.

But halting progress, ever-more deadly drone attacks and unmoving negotiating positions seem to have taken their toll. On Thursday, Trump used a striking analogy to concede the warfare was nowhere near over, and that he did not, at that moment, feel it was best to intervene.
