Frustrated with Russian President Vladimir Putin, former US President Donald Trump has issued a 50-day ultimatum to end the war in Ukraine, warning of imposing 100% sanctions on Russia if hostilities continue. In a phone call with Ukrainian President Volodymyr Zelensky, Trump reportedly asked whether Ukraine could strike Moscow and St. Petersburg, to which Zelensky responded affirmatively if supplied with adequate weapons. Trump also pledged to provide Ukraine with the Patriot missile defense system. Meanwhile, Russia warned that Trump’s aggressive rhetoric could prolong the war and escalate tensions. Analysts believe Trump’s shift in strategy stems from failed negotiations and Putin’s stubborn stance.
