India has rejected Pakistan's continuing veiled threats of using tactical nuclear missiles in the battlefield to deter Indian forces, holding that no one should be foolish enough to think of nuclear weapons as war-waging weapons. "Let's be quite clear on it... Nuclear weapons are not for war-fighting. They have got a strategic significance and that is where it should end," said Army chief General V K Singh, speaking on the sidelines of the 64th Army Day on Sunday.
