The US defense secretary, Lloyd Austin, has urged allies to "dig deeper" to support Ukraine at a meeting of Nato and defense leaders in Germany, as pressure grows on Berlin to authorise its German-made Leopard 2 tanks to be sent from nations across Europe to Ukraine. However, so far Berlin has refused to budge.
Ukraine believes the tanks are vital to its ability to hold off Russia's invasion, and Western nations believe that – given their use by armies across Europe – they would provide the swiftest way to give Kyiv what it is crying out for. Once Berlin signs off on them being re-exported from other nations. So why does Kyiv rate them so?
