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.

Australia's government said on Saturday it had delivered M1A1 Abrams tanks to Ukraine as part of a A$245 million ($160 million) package to help the country defend itself against Russia in their ongoing war.

The Ukraine conflict has starkly illuminated the role of drones in modern warfare: both sides exchange hundreds of aerial strikes daily. Some of the most notable drone operations, such as Ukraine’s destruction of dozens of Russian strategic bombers in “Operation Spider’s Web,” might rewrite the future of warfare.
