Vladimir Putin has expressed hope that Russia will never have to use nuclear weapons against Isis.
At a meeting with defence chiefs in the Kremlin, the Russian president apparently championed the firing of cruise missiles from submarines in the Mediterranean.
State-funded Russia Today quotes Putin as saying:
We must analyse everything happening on the battlefield, how the weapons operate. The Kalibrs [sea-based cruise missiles] and KH-101 [airborne cruise missile] have proved to be modern and highly effective, and now we know it for sure - precision weapons that can be equipped with both conventional and special warheads, which are nuclear.
Naturally, this is not necessary when fighting terrorists and, I hope, will never be needed.
Earlier this week, before his proposed ban on Muslims entering the US dominated news agendas, Donald Trump's fellow Republican presidential hopeful Ted Cruz appeared to suggest a nuclear attack on the Middle East was needed to destroy Isis.
Speaking in Iowa, Senator Cruz said:
We will utterly destroy Isis. We will carpet bomb them into oblivion. I don’t know if sand can glow in the dark, but we’re going to find out [cheers from the crowd].
