question:
Passage: Strategic Air Command was formed by the United States Air Force after World War II to provide an active defense against any surprise attack by the Soviet Union. Though it had been an ally against Germany and Japan during World War II, by 1948 the Soviet Union showed a propensity to instigate problems with Britain, France and the United States. In August 1949, the Soviet Union detonated its first nuclear weapon and by the early 1950s had detonated a hydrogen bomb. The war of words between the two superpowers escalated during 1950s and 1960s into a nuclear arms race. By 1970 the United States was using a "Triad Defense System" composed of nuclear submarines armed with nuclear missiles, land based intercontinental ballistic missiles with nuclear warheads and bombers capable of delivering hydrogen bombs on enemy targets. The Boeing B-52 Stratofortress bomber had been designed in the early 1950s by Boeing Aircraft Company to give the United States Air Force the capability of delivering nuclear weapons far inside the territory of Soviet Russia. The planes were to fly at high altitude with enough fuel to hit their target. In May 1960, the Soviet Union made known its capability to shoot such high altitude planes out of the sky by using a surface to air missile to strike CIA pilot Francis Gary Powers' U-2 spy plane over Russian territory. From that point on, the high-altitude B-52 had to be modified to conduct missions at low level, something it was not intended to be.

question:
Passage: Gibson became involved in politics as a member of the Whig Party with strong anti-slavery views. During the U.S. Presidential campaign of 1844, he gave stump speeches for Henry Clay due to the Whig Party's platform that opposed admitting Texas into the Union because it was a slave state. In the U.S. Presidential campaign of 1848, Gibson supported Whig candidate, "Rough and Ready" General Zachary Taylor. However, he was concerned about the Whig Party's lack of opposition to the abolition of slavery and personally visited Henry Clay at his home in Ashland, Kentucky in 1848 to discuss this issue. He lost as a Whig candidate for Ohio Attorney General in 1853. In 1853, following the large defeat of the Whig candidate General Winfield Scott in the U.S. Presidential election of 1852, Gibson threw his support to the Free Soil Party and began organizing what would become the Republican Party in Ohio. He attended the first organization meeting of the Republican Party in spring of 1856 in Pittsburgh. He was one of the 69 Ohio delegates (of a total 600 delegates from around the country) that attended the first Republican National Convention held in Philadelphia in June 1856. In 1856, he ran and was elected as the first Republican to hold the office of Ohio State Treasurer.
