Why is "Operation Brother Sam" trending?

Wikipedia Overview

Operation Brother Sam was the use of the United States Navy and Air Force in support of the coup in Brazil in 1964. With the deterioration in relations with João Goulart's government and the favorable attitude of the groups conspiring against him, the idea of an operation to ensure the success of an uprising arose. The issue was discussed between the U.S. ambassador to Brazil, Lincoln Gordon, and officials in Washington throughout the administration of president John F. Kennedy and his successor Lyndon B. Johnson. They thought about logistical support, the positioning of a squadron on the Brazilian coast to "show the flag" and even, in an extreme situation, a plan for a gigantic land operation, which was not used. The operation was planned by maintaining contact with Brazilian conspirators such as general Castelo Branco, and had as an assumption the formation of a provisional government that would request foreign aid.
