This opinion was expressed on Espreso TV by American diplomat John Herbst, former U.S. ambassador to Ukraine and now director of the Eurasia Center at the Atlantic Council."So far, Trump has been reluctant to take serious steps in response to Russia's ongoing aggression.But it's clear that over the past five or six weeks, Trump has pursued a policy of strength – first toward Iran, an ally of Russia, and also toward Russia itself. That was evident at the NATO summit. It was evident when Trump overruled the foolish decision made by our Defense Department to pause aid to Ukraine, aid that had been agreed to back during the Biden administration," Herbst explained.The diplomat is convinced that, in addition to pressuring Russia, Donald Trump’s administration will also strengthen secondary sanctions that would force India and China to stop buying Russian oil."It was also evident in the strong statement Trump made two weeks ago. So I think we're going to see serious sanctions. We are already seeing an energetic effort by the Trump team to get Patriot anti-missile defense systems to Ukraine over the past couple of weeks. And we've seen the Trump team pledge to send offensive weapons to Ukraine as well. I believe Trump is going to come down hard on the Kremlin. Hopefully, that will include secondary sanctions so that India, China, and other countries will decide to reduce substantially, if not completely, their purchase of contraband Russian oil and gas." he added.On August 6, Donald Trump’s special envoy Steve Witkoff arrived in Moscow. He met with Russian dictator Vladimir Putin, and their dialogue lasted about three hours. According to the U.S. president, the meeting was productive.The next day, Russia and the United States agreed on a meeting between leaders Vladimir Putin and Donald Trump. Later, the Russian dictator said that the UAE is the likely venue for talks with the U.S. leader, while calling a meeting with Volodymyr Zelenskyy possible but "still far off."
