Putin waves nuclear sword in confrontation with the West

It has been a long time since the threat of using nuclear weapons has been brandished so openly by a world leader, but Vladimir Putin has just done it, warning in a speech that he has the weapons available if anyone dares to use military means to try to stop Russia's takeover of Ukraine.

The threat may have been empty, a mere baring of fangs by the Russian president, but it was noticed. It kindled visions of a nightmarish outcome in which Putin's ambitions in Ukraine could lead to nuclear war through accident or miscalculation.

"As for military affairs, even after the dissolution of the USSR and losing a considerable part of its capabilities, today's Russia remains one of the most powerful nuclear states," Putin said, in his pre-invasion address early Thursday.

"Moreover, it has a certain advantage in several cutting-edge weapons. In this context, there should be no doubt for anyone that any potential aggressor will face defeat and ominous consequences should it directly attack our country."

By merely suggesting a nuclear response, Putin put into play the disturbing possibility that the current fighting in Ukraine might eventually veer into an atomic confrontation between Russia and the United States.

That apocalyptic scenario is familiar to those who grew up during the Cold War, an era when American schoolchildren were told to duck and cover under their desks in case of nuclear sirens. But that danger gradually receded from the public imagination after the fall of the Berlin Wall and the dissolution of the Soviet Union, when the two powers seemed to be on a glide path to disarmament, democracy and prosperity.

Before that, even young people understood the terrifying idea behind the strategy of mutually assured destruction -- MAD for short -- a balance in nuclear capabilities that was meant to keep hands on each side off of the atomic trigger, knowing that any use of the doomsday weapons could end in the annihilation of both sides in a conflict.

And amazingly, no country has used nuclear weapons since 1945, when President Harry Truman dropped bombs on Japan in the belief that it was the surest way to end World War II quickly. It did, but at a loss of about 2,00,000 mostly civilian lives in Hiroshima and Nagasaki. Around the world, even today, many regards that as a crime against humanity and question if it was worth it.

For a brief time after the war, the United States had a nuclear monopoly. But a few years after, the Soviet Union announced its own nuclear bomb and the two sides of the Cold War engaged in an arms race to build and develop increasingly more powerful weapons over the next few decades.

With the end of the Soviet Union in 1991, and its transformation to a hoped-for democracy under Boris Yeltsin, the United States and Russia agreed to limits on their armaments. Other post-Soviet countries like Ukraine, Kazakhstan and Belarus voluntarily gave up the nukes on their territory after the Soviet Union dissolved.

In recent years, if nuclear weapons were spoken of at all, it was usually in the context of stopping their proliferation to countries like North Korea and Iran. (Iran denies that it wants to possess them and North Korea has been steadily but slowly building both its nuclear weapons and its delivery mechanisms.)

When former U.S. President Donald Trump made an implicit threat to use nuclear weapons against North Korea in August 2017, many were shocked. Trump spoke before diplomacy and his fruitless summits with Kim began the following year. "North Korea best not make any more threats to the United States," Trump told reporters at his golf club in Bedminster, N.J.. "They will be met with fire and fury like the world has never seen." But North Korea's nuclear arsenal is far smaller than Russia's.

President Joe Biden has been aware of the danger of nuclear war between Russia and NATO since the emergence of the crisis with Ukraine. From the start, he has said NATO would not be sending troops into Ukraine because it could trigger direct fighting between the US and Russia, leading to nuclear escalation and possibly World War III.

It was a tacit admission that the United States would not take on the Russians militarily over Ukraine, and instead rely on extraordinary sanctions to gradually strangle the Russian economy.

But the admission also included another truth. When it came to fighting off a Russian invasion, Ukraine remained on its own because it is a non-treaty member and does not qualify for protection under NATO's nuclear umbrella.

If Putin tried to attack one of America's NATO partners, however, that would be a different situation, because the pact is fully committed to mutual defence, Biden has said.

Knowing that Biden had already taken a military response off the table, why did Putin even bother to raise it in his speech?

In part, he may have wanted to keep the West off-balance, to prevent it from taking aggressive action to defend Ukraine against Putin's blitzkrieg drive to take over the country.

But the deeper context seemed to be his great desire to show the world that Russia is a powerful nation, not to be ignored. Putin talks repeatedly about the humiliation of Russia after the Soviet collapse. By waving his nuclear sword, he echoed the bluster with which the Soviet Union had stared down the United States and earned, in his mind, respect.

After Putin's speech, Pentagon officials offered only a muted response to his implied threat to use nuclear weapons against any country that tried to intervene in Ukraine.
