Noting that terrorists have easier and cheaper ways of wreaking havoc, Menon said the nuclear weapons are complex
devises that are difficult to manage, use and deliver and require very high level of skills.
"To my mind, the real threat (to Pak nukes) is from insiders, from a Pakistani pilot or a brigadier who decides to
wage nuclear jihad, with or without orders," Menon writes in his book titled "Choices: Inside the making of India's Foreign Policy."
"The risk increases as Pakistan builds tactical nuclear weapons for battlefield use, control of which will necessarily
be delegated down the command chain," he said. Menon says Pakistan is the only nuclear weapon programme
in the world that is exclusively under military control "There are good reasons why no other country chose to go
down this path," he said.
Menon writes that India has nuclear weapons for the contribution that make to its national security in an
uncertain and anarchic world by preventing others from attempting nuclear blackmail and coercion against India.
"Unlike in certain NWS, India's nuclear weapons are not meant to redress a military balance, or to compensate for some perceived inferiority in conventional military terms, or to serve some tactical or operational military need on the battlefield," he notes.
While India has a declared policy of no-first use of nuclear weapons, Menon in his book warns that if Pakistan were
to use tactical nuclear weapons against India "even against Indian forces in Pakistan," it would effectively be opening
the door to a massive Indian-first strike, having crossed India's declared red line."Pakistani tactical nuclear weapons use would effectively free India to undertake a comprehensive first strike against
Pakistan," he said."There are several responses short of war available to astate like India," he writes.
