U.S.-Russia nuclear war: Is World War 3 happening? What we know so far
Russia and the USA have exchanged nuclear threats which have raised apprehensions over whether there will be World War III or not.

Nuclear Threats
The number of Russian nuclear submarines in the world's oceans is significantly higher than the American ones, and the subs that US President Donald Trump ordered to be redirected to the appropriate regions have long been under their control. So no response from the Russian Federation to the American leader's statement about the submarines is required, a senior Russian lawmaker, Viktor Vodolatsky, was quoted as saying by TASS.
Earlier on Friday, Trump wrote on his Truth Social post that he had ordered the redeployment of US submarines "to appropriate regions" allegedly over "extremely provocative statements" by former Russian President Dmitry Medvedev, who is also the deputy chairman of the Russian Security Council.
The United States has a total of 14 Ohio Class nuclear-powered submarines, each capable of carrying up to 24 Trident II D5 ballistic missiles that can deliver multiple thermonuclear warheads up to 4,600 miles. Between 8 and 10 Ohio Class submarines are deployed at any one time, according to the Nuclear Threat Initiative arms control group.
Russia currently operates 54 nuclear-powered submarines, including both strategic and attack types, out of an overall submarine force of about 79 vessels. 14 nuclear-powered ballistic missile submarines (SSBNs)—Russia’s sea‑based nuclear deterrent—comprise eight modern Borei‑class (Project 955/955A) and six older Delta III/IV boats. 13 nuclear-powered guided‑missile submarines (SSGNs), including six Oscar II‑class and seven Yasen‑class (Project 885/885M), serve as precision strike platforms with cruise- and hypersonic‑capable munitions. 16 nuclear-powered attack submarines (SSNs)—primarily upgraded Akula‑class and a few Sierra‑class boats used for anti‑submarine warfare and sea denial missions.
World War 3?
"Let the two US subs sail, they have been in the crosshairs for a long time now," the Russian lawmaker said. "A fundamental agreement that must be concluded between Russia and America so that the whole world calms down and stops talking about the beginning of World War III," he added.
Trump posted on his social media site that, based on the “highly provocative statements” from Medvedev, he had “ordered two Nuclear Submarines to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that.” The president added, “Words are very important, and can often lead to unintended consequences, I hope this will not be one of those instances.”
Meanwhile, editor-in-chief of Russia in Global Affairs magazine, Fyodor Lukyanov, said that Trump's nuclear submarine statement should not be taken seriously for now.
Earlier, responding to a media question over US State Department Secretary Marco Rubio's recent interview with Fox News, Russian Foreign Minister Sergei Lavrov said that Russia agrees with the US administration that a direct military confrontation between Moscow and Washington must not happen.
It wasn’t clear what impact Trump’s order would have on U.S. nuclear subs, which are routinely on patrol in the world’s hotspots, but it comes at a delicate moment in the Trump administration's relations with Moscow.
Trump has said that special envoy Steve Witkoff is heading to Russia to push Moscow to agree to a ceasefire in its war with Ukraine and has threatened new economic sanctions if progress is not made. He cut his 50-day deadline for action to 10 days, with that window set to expire next week.
Any talk by a U.S. president about potential nuclear military capabilities raises concerns, the security experts said, noting that the United States has historically refrained from matching Russia's nuclear-saber rattling given the risks surrounding the world's most devastating weaponry.
"This is irresponsible and inadvisable," said Daryl Kimball, executive director of the Arms Control Association advocacy group. "No leader or deputy leader should be threatening nuclear war, let alone in a juvenile manner on social media."
Hans Kristensen of the Federation of American Scientists noted that U.S. nuclear submarines – part of the so-called nuclear triad with bombers and land-based missiles – were always positioned to launch nuclear-armed missiles at targets in Russia.
"The subs are always there all the time and don't need to be moved into position," he said. "He grants Medvedev a response to these crazy statements."
