Political strategist Taras Zahorodnii said this on the air of Espreso TV."He will definitely have to do something, because Trump loudly announced to the whole world that he would act. If he does nothing, he will look like an empty talker. So he will definitely do something – we just don’t know what. That, by the way, also creates uncertainty for Russia," Zahorodnii said.Zahorodnii outlined two possible scenarios the U.S. could pursue."Either they impose a full trade blockade on Russia, and they can do that with their capabilities. Banks that process Russian payments could be sanctioned. Then it would be quite effective. As they are currently pressuring banks in Turkey and the United Arab Emirates. That’s within their power, because all of Russia’s sanction-evasion routes are already known. Increasing aid to Ukraine is also possible. In principle, when Americans want to, they can do a lot," the political strategist added.Trump’s deadline for PutinOn July 28, Donald Trump said he was disappointed with Vladimir Putin and planned to shorten the previously set 50-day timeframe for peace with Ukraine.On July 28, Dmitry Medvedev threatened war with the US in response to Trump shortening the deadline to 10–12 days for Putin to make peace with Ukraine.On July 29, the U.S. president confirmed he had reduced the deadline for the Russian dictator to reach a ceasefire in Ukraine to 10 days.On July 31, President Donald Trump responded to Medvedev’s threats, while US Secretary of State Marco Rubio called Medvedev an “irrelevant figure” in Russian politics.On August 5, Trump said that if oil prices drop, Russia would stop the war in Ukraine, because dictator Vladimir Putin "will have no choice."
