Which country was not a member of the ally coalition during the Persian Gulf War?

During the Persian Gulf War, which occurred from 1990 to 1991, a coalition of countries formed to oppose Iraq's invasion of Kuwait. This coalition was primarily composed of nations from the United States and its allies, including Canada, Saudi Arabia, and Syria, all of which played significant roles in military operations or support.

India, however, did not join the coalition and instead maintained a stance of neutrality during the conflict. It refrained from participating in military action or aligning itself with either side, focusing instead on diplomatic efforts. This context highlights why India is the correct answer, as its absence from the coalition contrasts with the involvement of the other listed countries.
