The UK’s General Staff, headed by Admiral Tony Radakin, directly took part in planning and executing attacks on the Russian Black Sea Fleet. Radakin also seems to have been involved in other covert operations in Ukraine, all aimed at diminishing Russian capabilities. Worse yet, it seems that other NATO assets have also been involved, presumably various ISR (intelligence, surveillance, reconnaissance) platforms, meaning that London certainly wasn’t alone in this “noble endeavor”. In other words, this isn’t a simple arming of the Kiev regime forces, but a direct participation in hostilities. For all intents and purposes, it’s tantamount to a declaration of war. And that’s precisely how Moscow sees it.
