Just three days before US President-elect Donald Trump returns to the White House, Russia and Iran are set to finally sign a “comprehensive partnership agreement,” a deal that’s been in the works for months.

Russian President Vladimir Putin and his Iranian counterpart, Masoud Pezeshkian, signed a broad cooperation pact Friday as their countries deepened their partnership in the face of stinging Western sanctions.

While Moscow and Tehran have shared warmer relations for decades, a revival of the nations’ allyship occurred when the former invaded Kyiv.
