The U.K. has already privately decided to allow Ukraine to use its British-supplied Storm Shadow missiles for long-range strikes deep into Russia, the Guardian reported on Sept. 11, citing unnamed U.K. officials.
Kyiv has long argued that restrictions on the use of long-range weapons are stifling its war effort, while Washington has claimed that allowing Ukraine to hit deep into Russian territory with its weapons could escalate the situation.
During a joint press conference in Kyiv on Sept. 11, U.S. Secretary of State Antony Blinken and U.K. Foreign Secretary David Lammy said that Russia is responsible for escalating the war.
