In speaking to Russian media, Medvedev, who now serves as deputy chairman of the Russian Security Council, scoffed at current Western leaders whom he says are not nearly as forward-thinking as their predecessors.
"They have made a miscalculation, since they are not of the brightest kind," Medvedev said.
"For some reason they think that Russians will never cross a certain line. They are wrong. If it comes down to the existence of our state, as the president of our country has repeatedly said ... we will simply have no choice."
No matter who is in charge of a nuclear-armed state like Russia, whether it is Vladimir Putin or somebody else, has an obligation to defend his country "to the last man," Medvedev continued.
Western leaders like French President Emmanuel Macron and German Chancellor Olaf Scholz both "lack the acumen and subtlety of mind" to handle international affairs the way those who came before them did.
"The political class is degenerating," Medvedev continued. "Technocrats are coming in and they cannot understand how politics function. This is a disaster."

It would seem as though Putin himself inspired Medvedev's words, seeing as how Russia's current leader back in September proposed amending Russia's nuclear doctrine to expand the scenarios in which Moscow can respond to aggression with nuclear weapons.
In the case of Ukraine, which does not, as far as the world knows, have any nuclear weapons, Putin wants to be able to attack the United States, a nuclear-armed nation, with nuclear weapons in the event that it helps Ukraine attack territory deep within Russia.
The fact that the West recently proposed having Ukraine conduct long-range strikes on Russian territory is proof-positive that this is NATO itself "waging war" against Russia, Medvedev warns.
To prepare for an upcoming nuclear attack, Russia recently launched military exercises to test the use of cruise and intercontinental ballistic missiles. Putin said the drills are necessary to maintain Russia's nuclear capabilities at a "sufficient level" as the war rages on.
While Moscow has no intention of getting involved in another "arms race," Putin clarified that Russia will use nuclear weapons as a "last resort" to keep its enemies in check while maintaining its own national security.
The likelihood of any nation actually pulling the trigger on using nukes still seems minimal, though, at least in terms of the nations of the world trying to preserve it from massive nuclear fallout.
"Israel and Russia likewise will not be easily nuked since both own what others crave: Jerusalem and the oil, gas, and mineral fields in Russia," one commenter wrote.
"Nuking will make it totally unobtainable for thousands of years and those that use this road will be removed from the globe in a wink. What might be used is AI. Even the Bible talks about unstoppable soldiers. But then, the Creator knows everything even how to stop the devil when necessary. Trust Him!"
Another wrote that the "deep state via the neo-cons" are in control of NATO, the various non-governmental organizations (NGOs) that fund it, and the three-letter intelligence agencies of the world.
"The fight has not even started," this person added, suggesting that Donald Trump is in the same kind of "danger" as John F. Kennedy was before the powers that be (TPTB) had him offed.
