At the start of this week, Britain announced it plans to provide Ukraine with classified technology to allow for the country's own manufacturing of the British/French-designed SCALP air-launched cruise missile (which in the UK is known as the Storm Shadow). The allies expect to set up a production line in Ukraine as soon as year's end.

Already, Ukraine has used its domestic-made and designed Neptune cruise missile to strike oil refineries and military sites deep inside Russian territory. A domestic-made SCALP would present the likelihood of Ukraine then using this Western-designed missile to directly attack Russia, which only increases the chances of an eventual Moscow-NATO clash. Ukrainian forces already appeared to have used the missile on Donetsk and other locations closer to front lines in the Donbass.

On Thursday the Kremlin has issued one of its strongest warnings and threats aimed at London to date, accusing the UK of "fully taking part in the war on Kiev's side" - and thus thwarting any chance of peace talks while adding fuel to the fire.

Moscow is now saying that the UK's own military facilities could become fair game for direct attacks.

Kremlin spokesperson Maria Zakharova said in a Thursday press briefing, "We have repeatedly warned that the response to Ukrainian strikes using British weapons against Russian territory could be directed against any British military facilities and equipment in Ukraine and beyond."

Zakharova urged "all residents of the United Kingdom to think about the inevitable, catastrophic consequences of the hostile steps taken by their own authorities." She also laid out:

"We propose that the British leadership once again carefully analyze the situation and immediately, in the most resolute and unequivocal manner, abandon the hostile, aggressive line, which can only... create the risk of the conflict escalating to an entirely new level."

Ironically this comes just on the heels of a rare visit of the CIA Director to Moscow. US officials claim the Tuesday meeting between John Ratcliffe and top Kremlin intelligence officials was to convey a warning to President Putin to not attack any NATO member. However, many analysts are skeptical that this was the official reason.

Zakharova further said on Thursday that Britain and France were "playing ?with ?fire" after years of escalating their involvement in Ukraine.

But London appears unmoved, with a UK Ministry of Defence official responding on Thursday as follows: "Britain stands shoulder to shoulder with Ukraine and we are committed to providing the equipment Ukraine needs to defend itself against Putin's illegal invasion. Russia should be in no doubt about the resolve of this government to stand against Russian aggression, in Ukraine and against the UK and our allies," the official stated.
