India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 160 nuclear weapons and has produced enough weapons-grade plutonium for up to 200 nuclear weapons. In 1999, India was estimated to have of separated reactor-grade plutonium, with a total amount of of civilian plutonium, enough for approximately 1,000 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely Pokhran I and Pokhran II. India is a member of three multilateral export control regimes — the Missile Technology Control Regime, Wassenaar Arrangement and Australia Group. It has signed and ratified the Biological Weapons Convention and the Chemical Weapons Convention. India is also a subscribing state to the Hague Code of Conduct. India has signed neither the Comprehensive Nuclear-Test-Ban Treaty nor the Nuclear Non-Proliferation Treaty, considering both to be flawed and discriminatory. India previously possessed chemical weapons, but voluntarily destroyed its entire stockpile in 2009 — one of the seven countries to meet the OPCW extended deadline. India maintains a "no first use" nuclear policy and has developed a nuclear triad capability as a part of its "Minimum Credible Deterrence" doctrine. Biological weapons India has ratified the Biological Weapons Convention (BWC) and pledges to abide by its obligations. There is no clear evidence, circumstantial or otherwise, that directly points toward an offensive BW program. India does possess the scientific capability and infrastructure to launch an offensive BW program. In terms of delivery, India also possesses the capability to produce aerosols and has numerous potential delivery systems ranging from crop dusters to sophisticated ballistic missiles. No information exists in the public domain suggesting interest by the Indian government in delivery of biological agents by these or any other means. To reiterate the latter point, in October 2002, the then President A. P. J. Abdul Kalam asserted that "India will not make biological weapons. It is cruel to human beings". Chemical weapons In 1992, India signed the Chemical Weapons Convention (CWC), becoming one of the original signatories of the CWC in 1993, and ratified it on 2 September 1996. According to India's ex-Army Chief General Sundarji, a country having the capability of making nuclear weapons does not need to have chemical weapons, since the dread of chemical weapons could be created only in those countries that do not have nuclear
