 | | As one of the five recognized nuclear weapons states under the Nuclear Non-Proliferation Treaty (NPT), the United States maintains a sizeable arsenal of nearly 10,000 nuclear warheads, of which nearly 6,000 are operational and the remainder in reserve or inactive stockpiles. |
 | | The United States ratified the Geneva Protocol in 1975, with the reservation that the treaty not apply to defoliants and riot control agents such as were used in Vietnam and Laos during the Vietnam War. |
 | | Currently, the United States has what is believed to be the world's second largest stockpile of chemical weapons, including bombs, rockets, and artillery shells that are loaded with lewisite, mustard, sarin, soman, VX, or binary nerve agents. |
