Diplomat and former Ukrainian Foreign Minister (2007–2009), head of the Center for Russian Studies, Volodymyr Ohryzko, shared his opinions on Espreso TV."As always, there are two options: one good, the other bad. The good one is that Trump, despite all his inconsistencies, might actually see things through to the end, and Russia will finally get what it should have received long ago, namely, rather tough sanctions that will finish off the already half-dead, excuse the expression, Russian economy. Option number two: Witkoff, who, as Trump has apparently just announced, will arrive in Moscow just before the end of this ultimatum, brings something back to Trump, and Trump says, 'Well, I've changed my mind, I’ll give another 50 days, or 20, or 40, or however many there were.' I don’t rule that out either, because we’re dealing with a fairly unpredictable politician who changes his position rather quickly. So let’s try to stay optimistic," he said.Volodymyr Ohryzko believes that Russian leader Vladimir Putin has crossed all possible red lines of U.S. President Donald Trump’s patience.“I think Putin has overstepped every boundary of Trump’s patience — he humiliated him openly, constantly, and publicly. And I don’t think Trump forgives things like that. Let’s also not forget how suddenly Trump paid attention to Medvedev’s crazy statements. Previously, if we analyze Trump’s reactions, he barely acknowledged Medvedev or understood who he was. And now he suddenly noticed. I think that’s just a formal pretext to show Putin: ‘Look, I also have nuclear weapons, and I can use them too if needed, but that would mean your political and physical end.’ So let’s wait, only a few days remain. I still hope Trump will show himself as a true leader,” the diplomat stressed.On July 14, Donald Trump announced he would impose secondary tariffs of up to 100% on Russia if a peace deal with Ukraine is not reached within 50 days.On July 28, Donald Trump said he was disappointed with Vladimir Putin and planned to shorten the 50-day deadline for the ceasefire with Ukraine that he had previously set.On July 28, Dmitry Medvedev threatened war with the U.S. in response to the reduced deadline of 10–12 days that Donald Trump gave Putin to make peace with Ukraine.
