The U.S. has been Ukraine’s biggest military backer since Russia’s full-scale invasion began three years ago. The suspension of that aid by the Trump administration doesn’t mean Ukraine’s defenses will quickly collapse.

Washington's suspension of military assistance will not lead to a sudden collapse of Ukraine's defensive lines, but it could have a real impact on the war within months, undermining air defences and precision strike capabilities in particular.

Trump is ramping up his attacks on President Volodymyr Zelenskyy and U.S. financial support for Ukraine's war against Russia.
