The recent escalation of the Russia-Ukraine war has led to increasing talk of nuclear war, especially following repeated threats from Russian President Vladimir Putin against NATO countries. Newsweek looked at the impact of a Russian nuclear weapon on the capitals of U.S. NATO allies.
In September, Putin lowered the threshold of nuclear weapon use by saying: "This includes strategic and tactical aircraft, as well as cruise missiles and drones, hypersonic and other delivery vehicles. Russia reserves the right to use nuclear weapons in case of aggression, including if the enemy using conventional weapons poses a critical threat."
Since then, the U.K is believed to have granted permission for Ukraine to fire missiles supplied by London's defense ministry into Russian territory.
Newsweek used maps produced by Alex Wellerstein, a professor and historian of nuclear technology, to assess what the impact would be if Moscow attacked with its R-36M2 (also known as the SS-18 Satan), one of the largest and most powerful heavy intercontinental ballistic missiles (ICBM) ever built.
It can yield the equivalent of 20 megatons (20,000 kilotons) of TNT explosives and has a range of up to 10,000 miles.
The fireball radius (inner yellow circle), in which everything would be vaporized by intense heat rising to millions of degrees F, would reach around 15.1 square miles. The more moderate blast damage radius (inner gray circle), covering 442 square miles of the blast, would destroy residential buildings and probably cause widespread fires.
Anyone within 2,360 square miles of the explosion (the thermal radiation radius: wider orange circle) would be at risk of suffering third-degree burns throughout the skin, "often painless because they destroy the pain nerves," which can cause severe scarring, disablement and require amputation.
Within the light blast damage radius (wider gray circle), 3,490 square miles from the blast, glass windows should be expected to break, which can cause injuries.

Newsweek has contacted the defense departments for the U.S. and Russia, via email, for comment. It has also contacted NATO, via online contact form, for comment.

The Context
There is currently much talk about nuclear war as conflict escalates between the U.S. and its NATO allies and Russia over the war in Ukraine.
Russian president Vladimir Putin recently signed an updated nuclear doctrine into law which emphasizes that Russia will make "all necessary efforts to reduce the nuclear threat" and aims to prevent escalating tensions between states that could lead to "military conflicts, including nuclear ones."
It also says that nuclear deterrence should also ensure "an understanding by a potential adversary of the inevitability of retaliation in the event of aggression against the Russian Federation and (or) its allies."
Ukraine used U.S.-made ATACMS missiles against a target inside Russia for the first time last week, after President Joe Biden allowed such usage.
This followed Moscow's deployment of North Korean troops to the front lines in the Kursk region, an action described by the Biden administration as a significant escalation of the conflict.
On Tuesday, Dmitry Medvedev, the Deputy Chairman of the Security Council of Russia and former Russian president said the U.S. was "seriously discussing the consequences of transferring nuclear weapons to Kyiv" but the White House told Newsweek: "We are not planning to equip Ukraine with nuclear weapons."
