Gasden Purchase--the strip of land purchased from Mexico in 1853 was negotiated by James Gasden.
The US wanted this strip of land to complete the southern branch of the Transcontinental Railroad. Gasden was the minister to Mexico and sent to negotiate the purchase of the land as well as create a final border agreement with Mexican president, Santa Anna. The land was purchased for $10 million and settled the US-Mexico border.
President Anwar Sadat of Egypt had worked together with Israel's prime minister Menachem Begin, at the urging of US President Jimmy Carter. They met at Camp David in the US for 12 days in September of 1978, and worked out the Camp David Accords. Egypt and Israel later signed the Egypt-Israel Peace Treaty in March of 1979 -- a peace between Egypt and Israel that has lasted to the present day.
Sadat, however, paid a price for his peace efforts. Islamist activists in Egypt heatedly opposed him because of his moderation. Sadat was assassinated in October, 1981.
