Putin’s refusal to compromise on Ukraine, say analysts, is a colossal error costing Russia regional influence, lucrative energy markets and its place in the world.

Former Secretary of State Condoleezza Rice said she believes “this last week was a turning point” in the U.S. and European stance toward Ukraine and Russia.

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