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.

Ukraine has taken possession of most of the 49 tanks given by Australia, and the rest will be delivered in coming months, said Defence Minister Richard Marles. “The M1A1 Abrams tanks will make a significant contribution to Ukraine’s ongoing fight against Russia’s illegal and immoral invasion," Marles said in a statement.

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.
