The U.S. responded to Russian President Vladimir Putin's announcement of new nuclear weapons on Thursday, with the State Department saying it was proof that Russia has been developing destabilizing weapons in direct violation of its international commitments.
State Department spokeswoman Heather Nauert said Putin's speech showed Russia had violated its obligations under the Intermediate-Range Nuclear Forces treaty.
She also criticized an animated video played during his remarks, saying it appeared to depict an attack on the United States.The video had computer simulations of the new weapons, shown on giant screens at a conference hall near the Kremlin.

The State Department called the video "unfortunate," and not the "behavior of a responsible international" party.
The Pentagon also downplayed the incident saying Moscow's weaponry was long under development and had already been factored into U.S. assessments.
"We're not surprised by the statements and the American people should rest assured that we are fully prepared," said Pentagon spokeswoman Dana White, after Putin, speaking ahead of a March 18 election, showcased missiles that he said could hit almost any point in the world.
Russia has tested an array of new strategic nuclear weapons that can't be intercepted, Putin announced Thursday, marking a technological breakthrough that could dramatically increase Russia's military capability, boost the Kremlin's global position and also raise Western concerns about a potential renewed arms race in the 21st century.
Speaking in a state-of-the-nation speech, Putin said the weapons include a nuclear-powered cruise missile, a nuclear-powered underwater drone and new hypersonic missile that have no equivalent elsewhere in the world. He said the creation of the new weapons has made NATO's U.S.-led missile defense "useless," and means an effective end to what he described as Western efforts to stymie Russia's development.

"I want to tell all those who have fueled the arms race over the last 15 years, sought to win unilateral advantages over Russia, introduced unlawful sanctions aimed to contain our country's development: all what you wanted to impede with your policies have already happened," he said. "You have failed to contain Russia."
The announcement comes as Putin is set to easily win another six-year presidential term in the March 18 election.
He said that the nuclear-powered cruise missile tested last fall has a "practically unlimited" range and high speed and maneuverability allowing it to pierce any missile defense.
The Russian leader said the high-speed underwater drone also has an "intercontinental" range and is capable of carrying a nuclear warhead that could target both aircraft carriers and coastal facilities. He said its "very big" operational depth and a speed that is at least 10 times higher than any other vessel would make it immune to enemy intercept.
Putin accompanied his statement to an audience of hundreds of senior officials and lawmakers with videos and computer images of new weapons, which were shown on giant screens at a conference hall near the Kremlin.
A computer video showed the drone being launched by a submarine, cruising over the seabed, hitting an aircraft carrier and also exploding near the shore.
Putin noted that the tests of the compact nuclear reactor to power the new drone were completed last fall.
He added, to applause, that names for the nuclear-powered cruise missile and the drone haven't yet been chosen, and suggested that the Defense Ministry run a nationwide contest for the best names.
"No one in the world has anything like that," he said. "It may appear someday, but by that time we will develop something new."
The Russian leader said that another new weapon called Avangard is an intercontinental hypersonic missile that would fly to targets at a speed 20 times the speed of sound and strike "like a meteorite, like a fireball."
Putin said that the weapon is capable of performing sharp maneuvers on its way to targets, making it "absolutely invulnerable for any missile defense system."
Putin said that Russia also tested a new heavy intercontinental ballistic missile, called Sarmat, adding that its range allows it to fly over both the North and the South poles to reach any target. He said it carries more nuclear warheads than its Soviet-era predecessor, known in the West as Satan.
He said that another new weapons system, called Kinzhal, already has been deployed in Russia's Southern Military District. He added that it's a hypersonic missile carried by an aircraft that flies at a speed 10 times of the speed of sound and has a range of 2,000 kilometers (1,250 miles) away.
The Russian leader emphasized that the development of new weapons that have no equivalent in the West came in response to the U.S. withdrawal from a Cold war-era treaty banning missile defenses and U.S. efforts to develop a missile defense system.
He said that the U.S. has ignored Russian complaints.
"No one has listened to us," he said. "You listen to us now."
He emphasized that Russia is concerned about the Pentagon-led nuclear review released earlier this year that envisaged the development of low-yield nuclear weapons, saying that it could lower the threshold for using nuclear weapons.
"We will interpret any use of nuclear weapons against Russia and its allies no matter how powerful they are, of low, medium or any other yield, as a nuclear attack," he said. "It will trigger an immediate answer with all the consequences stemming from it. No one should have any doubts about it."
He said that Russian military experts and diplomats would be ready to discuss new weapons systems with their U.S. counterparts.
"We aren't threatening anyone, we aren't going to attack anyone, we aren't going to take anything from anyone," he said. "The growing Russian military power will guarantee global peace."
