1956 – The United States conducts the first airborne test of an improved hydrogen bomb, dropping it from a plane over the tiny island of Namu in the Bikini Atoll in the Pacific Ocean. The successful test indicated that hydrogen bombs were viable airborne weapons and that the arms race had taken another giant leap forward. The United States first detonated a hydrogen bomb in 1952 in the Marshall Islands, also in the Pacific. However, that bomb–and the others used in tests that followed–were large and unwieldy affairs that were exploded from the ground. The practical application of dropping the weapon over an enemy had been a mere theoretical possibility until the successful test in May 1956. The hydrogen bomb dropped over Bikini Atoll was carried by a B-52 bomber and released at an altitude of more than 50,000 feet. The device exploded at about 15,000 feet. This bomb was far more powerful than those previously tested and was estimated to be 15 megatons or larger (one megaton is roughly equivalent to 1 million tons of TNT). Observers said that the fireball caused by the explosion measured at least four miles in diameter and was brighter than the light from 500 suns. The successful U.S. test meant that the ante in the nuclear arms race had been dramatically upped. The Soviets had tested their own hydrogen bomb in 1953, shortly after the first U.S. test in 1952. In November 1955, the Soviets had dropped a hydrogen bomb from an airplane in remote Siberia. Though much smaller and far less powerful (estimated at about 1.6 megatons) than the U.S. bomb dropped over Bikini, the Russian success spurred the Americans to rush ahead with the Bikini test. The massive open-air blast in 1956 caused concerns among scientists and environmentalists about the effects of such testing on human and animal life. During the coming years, a growing movement in the United States and elsewhere began to push for a ban on open-air atomic testing. The Limited Test Ban Treaty, signed in 1963 by the United States, the Soviet Union, and Great Britain, prohibited open-air and underwater nuclear testing.
1959 – Japanese-Americans regained their citizenship.
1964 – France proposes reconvening a 14-nation conference on Laos in Geneva; it is rejected by the United States and Great Britain but accepted by the Soviets, Poland, Cambodia, India, and Communist China.
1969 – After 10 days and 10 bloody assaults, Hill 937 in South Vietnam is finally captured by U.S. and South Vietnamese troops. The Americans who fought there cynically dubbed Hill 937 “Hamburger Hill” because the battle and its high casualty rate reminded them of a meat grinder. Located one mile east of the Laotian border, Hill 937 was ordered taken as part of Operation Apache Snow, a mission intended to limit enemy infiltration from Laos that threatened Hue to the northeast and Danang to the southeast. On May 10, following air and artillery strikes, a U.S.-led infantry force launched its first assault on the North Vietnamese stronghold but suffered a high proportion of casualties and fell back. Ten more infantry assaults came during the next 10 days, but Hill 937’s North Vietnamese defenders did not give up their fortified position until May 20. Almost 100 Americans were killed and more than 400 wounded in taking the hill, amounting to a shocking 70 percent casualty rate. The same day that Hamburger Hill was finally captured, Senator Edward Kennedy of Massachusetts called the operation “senseless and irresponsible” and attacked the military tactics of President Richard Nixon’s administration. His speech before the Senate was seen as part of a growing public outcry over the U.S. military policy in Vietnam. U.S. military command had ordered Hill 937 taken primarily as a diversionary tactic, and on May 28 it was abandoned. This led to further outrage in America over what seemed a senseless loss of American lives. North Vietnamese forces eventually returned and re-fortified their original position.
1970 – More than 100,000 construction workers, dock men, and office workers lead a parade in New York City supporting the policies of President Nixon and attacking Mayor John Lindsay and other opponents of the Vietnam War.
1970 – About 2,500 South Vietnamese soldiers, supported by US airpower and advisors, open up a new front in Cambodia, 125 miles north of Saigon, bringing the number of South Vietnamese troops in Cambodia to 40,000. South Vietnamese troops link up with Cambodian forces 25 miles north of Takeo after a cross country drive.
1972 – President Nixon meets with Leonid Brezhnev for summit talks in Moscow. Although Vietnam is discussed, there is no change in the Soviet Union’s support of North Vietnam, and both parties are apparently unwilling to risk détente over the topic.

Shortly after the agreement, the White House announces its decision to allow U.S. oil companies to purchase Iraqi oil exports.
1997 – Marine Corporal Clemente Banuelos shot and killed the goat herder Esequiel Hernandez on the Mexican border at El Paso while on border patrol. The marine claimed self-defense after Hernandez fired 2 shots from a .22-caliber rifle. A grand jury later declined to indict Banuelos.
1999 – The CGC Bear arrived in Rota, Spain. She was deployed to the Adriatic Sea in support of “Operation Allied Force” and “Operation Noble Anvil”, NATO’s military campaign against the forces of the former Republic of Yugoslavia. Bear served in the USS Theodore Roosevelt Battle Group providing surface surveillance and SAR response for the Sea Combat Commander, and force protection for the Amphibious Ready Group operating near Albania. Bear provided combat escort for U.S. Army vessel’s transporting military cargo between Italy and Albania. This escort operation took Bear up to the Albanian coastline, well within enemy surface-to-surface missile range.
