Former British Prime Minister David Cameron, now the country's foreign minister, said that Ukraine "absolutely has the right" to launch missile strikes into Russian territory with British weapons on Thursday.
Lord Cameron made the remarks as he made his second visit to the Ukrainian capital as foreign secretary and as Britain promised Ukraine that it would provide it with £3B ($3.8B) in military aid every year "for as long as it takes."
Just as Russia has been launching strikes inside Ukraine, if Ukrainians feel that they are better able to defend themselves by striking troop concentrations and logistics nodes inside Russian territory, they are justified in doing that to achieve their war objectives.
Aside from the avoidable loss of Ukrainian territory and men throughout this conflict, Ukraine's counteroffensive has failed and Kyiv is now losing the war. More money for arms will simply bring about more death and destruction. Ukraine would never have fought this war against Russia without US and EU weapons.
