Answer :
The accurate reason why Congress added "Under God" in the pledge of allegiance in 1954 was:
1. To distinguish the United States from the Soviet Union: The addition of "Under God" in the pledge of allegiance was primarily in response to the perceived atheistic stance of the Soviet Union during the Cold War. The United States wanted to differentiate itself as a nation that embraced religion and believed in the existence of a higher power.
By adding "Under God" to the pledge, Congress aimed to emphasize the country's commitment to religious values and to counter the atheistic image associated with the Soviet Union. This addition was seen as a way to promote the idea of a nation founded on religious principles and to reaffirm the belief in God as a core aspect of American identity.
