AS sabre rattling goes, it takes some beating.
Vladimir Putin’s thinly-veiled threat to nuke the West and insistence that he is "not bluffing" has caused panic across the world.
Since the Cold War started, it has been assumed the threat of “mutually assured destruction” — in which tit-for-tat strikes would destroy both parties — would prevent a nuclear war.
However, in a chilling threat this week, the unhinged Russian leader declared: "When the territorial integrity of our country is threatened, we will use all the means at our disposal to defend Russia and our people, this is not a bluff."
With the dictator’s invasion of Ukraine meeting far stiffer resistance than expected and Western governments uniting against it, such desperate — and terrifying — measures appear more likely.
When Putin announced his invasion, he warned the West that it would face “consequences never encountered in your history” if Nato was to interfere militarily.

So, could the nightmare come true? Putin certainly has the hardware for every scenario.
At his disposal are an estimated 5,977 warheads, of which 1,600 are ready to be deployed. This terrifying arsenal can be launched from land, submarines and planes.
They include non-strategic “battlefield” nukes which have a smaller destructive power — and radioactive fallout — and are intended to destroy military capabilities rather than civilian populations. They can be anything from land mines to torpedos.
They have never been used in combat — so far.
