While it was unclear which ally Putin had in mind, the US-led North Atlantic Treaty Organisation said the speech, one of the Russian leader's most bellicose in years, did not help calm tensions that have surged since Russia seized Ukraine's Crimea four years ago.
So what new strategic weaponry does Russian Federation have, and how does this it enhance its military power?
Those claims are no bluff or idle threat, Professor Muraviev said, and are a further sign the world is locked in a military standoff more risky than the Cold War. Putin's "victory" in the fake election is in no doubt, so he doesn't really need a nuclear argument for Russians.
Nauert said Moscow had proven itself in violation of the 1987 Intermediate-Range Nuclear Forces Treaty (INF), through its development of ground-launched cruise missiles. The speech placed significant emphasis on Russia's growing military might, and as has always been a Russian tradition, seemed to pit that might against the United States as not only the measuring stick, but also the aggressor.
When asked whether Moscow would take action against the suspects, Putin said he could not "respond to that if they do not violate Russian law".
The suggestions include "Kraken" for a new underwater drone capable of blasting coastlines with a powerful nuclear explosion, and "Balalaika" for a futuristic nuclear-powered cruise missile capable of circling the globe.
Putin said the new missile is "like a fireball guided to its target" and also announced other state-of-the-art weapons in his state of the nation address in Moscow. Putin said trials began in December.
Just last month the United States cast Russian Federation as the main reason it needs to develop two new nuclear weapons: A lower-yield warhead for a submarine-launched ballistic missile and a sea-launched nuclear cruise missile.
The big difference between the missiles Russian Federation already has and the ones announced Thursday is that existing missiles are ballistic, whereas the new missiles would be cruise missiles.
But in his remarks, Putin maintained that Russia's military posture is purely defensive in nature.
Is it deployed? Unclear.
Jane's by IHS Markit noted that coming after the USA nuclear posture review Putin's statement "not only signals strength to a domestic Russian audience, but is a clear sign to the US that Russia will continue to modernize its nuclear forces to ensure their credibility".
Spokeswoman Heather Nauert told reporters it was "unfortunate" to have watched a video animation that depicted a nuclear attack on the United States.
"We do not want a new Cold War or a new arms race".
That grievance is nothing new.
In particular, Putin says Russian Federation has a new cruise missile, like a U.S. Tomahawk, but Russia's is equipped with a "small super powerful nuclear energy system" that will essentially let it fly forever.
The Pentagon spoke about Putin's display on Thursday, assuring, "We've been watching Russian Federation for a long time".
