Russia will target countries hosting US missiles if Washington goes ahead with plans to pull out of a landmark Cold War arms treaty, General Staff chief Valery Gerasimov said on Wednesday.

“If the INF treaty is destroyed, we won’t leave it without a response,” he said in a presentation to foreign military attaches in Moscow, according to an official transcript. “You as military professionals must understand that the target for Russian retaliation won’t be US territory but the countries where the intermediate-range missiles are deployed.”

His comments came hours after the US said it would pull out of the 1987 Intermediate-Range Nuclear Forces Treaty in 60 days if Russia doesn’t stop alleged violations. Moscow says it’s complying with the deal. Gerasimov accused the US of seeking to shift the blame for its demise to Russia.

While the INF treaty restricts the US and Russia, many other countries are producing these missiles and “apparently our American partners consider the situation has changed so much that the US has to have such weapons,” Russian President Vladimir Putin said, according to the Interfax news service. “What’s our response? It’s simple — in that case, we’ll also do it.”

The US has said it has no plans to deploy land-based nuclear missiles in Europe once it pulls out of the treaty. In the past, Russia has threatened to target European countries that hosted US missile defences.

Earlier Wednesday, the Defense Ministry said it’s deployed laser weapons, one of several systems Putin touted as a new generation of armaments during his annual address in March.

The Peresvet laser, named after a 14th century Orthodox monk who fought in single combat against a Tatar champion at the Battle of Kulikovo, was deployed by the army on December 1, the ministry said in an emailed statement.

Putin in March described the new arms as Russia’s response to the US decision in 2002 to pull out of the Anti-Ballistic Missile Treaty and develop its global defence shield. While Peresvet’s technical specifications are secret, military experts say it can be used against drones, missiles and aircraft.

Secretary of State Mike Pompeo told Nato allies on Tuesday that the US is setting a two-month deadline for Russia to return to compliance with the INF treaty before carrying out President Donald Trump’s threat in October to withdraw from the accord. Russia denies breaching the treaty, which bans deployment of ground-launched missiles with a range of 500km to 5,500km, and has said it wants to hold talks with the US on preserving the agreement.

“The US has presented no evidence that the Russian side in any way violates or fails to comply with the terms of the agreement,” Russian Foreign Ministry spokeswoman Maria Zakharova told reporters in Moscow. The INF treaty is “one of the key pillars of strategic stability” and Russia’s ready to discuss any problems with the accord without “baseless accusations and ultimatums,” she said.
