The United States has refused to back a joint statement by the Group of Seven (G7) nations condemning Russia’s missile strike on the Ukrainian city of Sumy, the deadliest in 2025. Washington’s decision, made April 15, was motivated by a desire to preserve space for negotiations with Moscow, but has caused division among allies. US President Donald Trump called the attack “horrible” but suggested Russia “made a mistake,” without elaborating. The lack of US support has made it impossible for the G7 to issue a statement, which under the group’s rules requires unanimity from all members.

The Trump administration’s decision reflects its desire for a diplomatic solution. Since returning to power in January 2025, Trump has stepped up contacts with Moscow, including through special envoy Steve Witkoff, who met with Vladimir Putin. But these efforts have so far failed to produce a breakthrough: a 30-day ceasefire has been rejected, and the strikes continue. For Ukraine and its European allies, Washington’s stance is perceived as weakening support for Kyiv, heightening tensions in the G7.
