Ukraine can use British-supplied weapons to strike targets inside Russia, UK Foreign Secretary David Cameron stated during a May 2 visit to Kyiv. “Ukraine has that right,” Cameron told Reuters. “Just as Russia is striking inside Ukraine, you can quite understand why Ukraine feels the need to make sure it’s defending itself.”
The British Foreign Secretary’s comments represent a departure from the cautious position adopted by most of Ukraine’s Western partners over the past two years. Since Russia’s full-scale invasion began in February 2022, the majority of countries backing Ukraine have insisted that Western weapons can only be used within Ukraine’s international borders and must not be deployed against targets inside the Russian Federation.
These restrictions reflect widespread concerns in Western capitals over a possible escalation of the current war into a far broader European conflict. Moscow has skillfully exploited the West’s fear of escalation, with Kremlin officials regularly warning of Russian red lines and Vladimir Putin making frequent thinly-veiled nuclear threats.
