Sir Keir Starmer ignored Vladimir Putin’s threats of nuclear war by insisting must be given “what it needs” to defeat .
The Prime Minister slammed the Kremlin’s “irresponsible rhetoric” and told Putin the “quickest way to end this conflict” is to withdraw their troops from Europe’s biggest land war since 1945.
Western allies – including Britain – are under intense pressure to allow to use long-range missiles to strike targets deep inside .
Moscow marked 1,000 days since its invasion by updating its weapons doctrine so that any large conventional attack on the Russian capital could meet the criteria for a nuclear response.

Sir Keir, asked if Brits needed to prepare for nuclear war, said: “There’s irresponsible rhetoric coming from .
“That is not going to deter our support for . We’re now on day 1,000 of conflict, 1000 days of Russian aggression, 1000 days of sacrifice in .
“We have stood with from the start. I’ve been doubling down on my message that we should give what is needs for as long as needed to win this war against Putin.
He added in earlier comments: “The quickest way to end this conflict is for to cease, and that is the quickest, most simple and just way to do this.”
He added in a separate interview: “This is a thousand days of conflict and there is a very high cost if Russian aggression is seen to pay off.
“A cost that we will all pay, because this is not just about sovereignty in , it’s about our freedoms.
“It’s about our way of life and it impacts everybody across the United Kingdom. But, you know, we are working of course with allies to make sure is in the best possible position.”
The changes to the nuclear doctrine came after Washington gave the green light for the use of US long-range missiles within and amid speculation that the UK could follow suit with British-supplied Storm Shadow weapons.
Shortly after the updates were rubber-stamped, Moscow’s defence ministry said had fired six US-made ATACMs missiles.
The ministry said it shot down five and damaged one more, in a statement carried by Russian news agencies.
Earlier on Tuesday, ‘s general staff said the Ukrainian army had carried out a strike on the arsenal of the 1046th logistics support centre in the area of Karachev in the Bryansk region.
Former Defence Secretary Grant Shapps warned Sir Keir’s inability to make a decision will bolster dictators around the world and cost thousands of lives.
The Prime Minister has still not lifted restrictions on Storm Shadow missiles, which can hit targets 150 miles away.
Asked about Storm Shadow missiles, Sir Keir said on Tuesday morning: “My position has always been that must have what it needs for as long as it needs. Putin must not win this war.
“But look, forgive me, I’m not going to go into operational matters, because there’s only one winner if I do that, and that is Putin and it would undermine Ukrainian efforts.
“I’m not going to do that. But here at the G20 and for many, many weeks, I’ve been making the case that must have what it needs for as long as it needs that we must put in the strongest possible position to win this war.
“It impacts , but it impacts all of us, and cannot be allowed to win this war.”
Ukrainian forces could now use the ATACMS to strike Russian and North Korean troops, key pieces of military equipment, ammunition depots, supply lines deep inside and logistics hubs.
Fears are intensifying that ’s forces could launch a major assault, with an estimated 50,000 soldiers, on Ukrainian positions in Kursk.
The Kremlin is believed to want to retake all of the Russian territory seized by Kyiv in August.
Dmitry Medvedev, who has been serving as deputy chairman of the Security Council of since 2020, said that in this case, this could amount to WW3.
He said: “The use of alliance missiles in this way can now be qualified as an attack by the bloc’s countries on .
“In this case, the right arises to launch a retaliatory strike with weapons of mass destruction against Kiev and the main NATO facilities, wherever they are. And this is already WWIII.”
America allowed Kyiv to use Army Tactical Missile Systems, (ATACMS), after North Korean troops joined Moscow’s soldiers in the conflict.
Dr Jack Watling, RUSI’s Senior Research Fellow for Land Warfare, said: “The question of escalation risk persistently lingers over this discussion. Unhelpfully, this has become stuck in a debate over whether any such weapon employment would lead to a nuclear response, which it certainly will not.
“The reality is that can escalate in a range of ways to impose costs on the West, from undersea sabotage to the employment of proxies to harass trade in the Bab el-Mandeb.”
“To be effective, [the ATACMS] use must be part of a wider strategy that targets a specific target set. This requires the coherent employment of ATACMS and munitions from other partners alongside ’s indigenous long-range strike systems. The Ukrainian military must also have a plan to exploit the effects achieved.”
Dr Watling concludes that, “most importantly, if deep strikes help to reduce the pressure on the front, Kyiv must use the resulting time to strengthen the line of defence.”
