US President Donald Trump’s 50-day pause ahead of possible secondary sanctions on Russia gifts the Kremlin a window to exploit the incremental gains of recent weeks in Ukraine’s east.

President Trump asked Ukrainian President Volodymyr Zelensky whether Kyiv was able to hit Moscow and St. Petersburg, according to a senior Ukrainian official familiar with their exchange in a July 4 phone call.
