According to CNN, U.S. Secretary of State Antony Blinken said on Sept. 27 that Ukraine "would be able to use" the weapons provided by the U.S. to regain its territory, including in Zaporizhzhia, Donetsk, Luhansk, and Kherson oblasts where Russia held its sham referendums.
"I've also been equally clear that Ukraine has the absolute right to defend itself throughout its territory, including to take back the territory that has been illegally seized in one way or another by Russia," Blinken said as quoted by CNN.
