Putin draws a nuclear red line for the West

LONDON: Russian President Vladimir Putin has drawn a "red line" for the United States and its allies by signalling that Moscow will consider responding with nuclear weapons if they allow Ukraine to strike deep inside Russia with long-range Western missiles.

But some in the West are asking: does he actually mean it?

The question is critical to the course of the war. If Putin is bluffing, as Ukraine and some of its supporters believe, then the West may feel ready to deepen its military support for Kyiv regardless of Moscow's threats.

If he is serious, there is a risk — repeatedly stated by Moscow and acknowledged by Washington — the conflict could turn into World War Three.

In the latest in a long series of warning signals, Putin on Wednesday extended the list of scenarios that could lead to Russia using nuclear weapons.

It could do this, he said, in response to a major cross-border conventional attack involving aircraft, missiles or drones. A rival nuclear power that supported a country attacking Russia would be considered a party to that attack.

Both those criteria apply directly to the situation that would arise if the West allows Ukraine to strike deep inside Russian territory with Western long-range missiles such as US ATACMS and British Storm Shadows, something Putin has said would need Western satellite and targeting support.

"It was a very clear message: 'Don't make a mistake — all these kind of things may mean nuclear war,'" said Nikolai Sokov, a former Soviet and Russian diplomat.

Bahram Ghiassee, a London-based nuclear analyst at the Henry Jackson Society think-tank, linked the timing of Putin's remarks to Ukraine's lobbying of the West for long-range missiles and the fact that President Volodymyr Zelenskiy is making his case to US President Joe Biden this week.

"Putin is saying: just stop it right there," Ghiassee said.

Reaction from Kyiv was swift, with Zelenskiy's chief of staff accusing Putin of "nuclear blackmail".

"In my opinion, this is yet another bluff and demonstration of Putin's weakness. He will not dare to use nuclear weapons because that will make him a complete outcast," Anton Gerashchenko, a former adviser to Ukraine's internal affairs minister, said on X.
