Russian President Vladimir Putin has sacrificed an estimated 1 million of his soldiers, killed and wounded, in a three-year campaign to crush Ukraine

President Trump now wants to give more weapons to Ukraine and is threatening increased sanctions if Russian President Vladimir Putin doesn't agree to end the war in 50 days. The president explained why in a phone call with our partners at BBC News.

In an interview by phone, President Trump told BBC Chief North America Correspondent Gary O’Donoghue that he is “not done” with Russian President Putin but is “disappointed in him” over the lack of a ceasefire deal with Ukraine.
