Which U.S. President was in office when the Gulf War began?

George H. W. Bush was the US President in office when the Gulf War began because during his presidency, Iraq, led by Saddam Hussein, invaded Kuwait on August 2, 1990.

President Bush demonstrated strong leadership and mobilized international support, resulting in a successful military campaign to liberate Kuwait. Therefore, it is clear that George H. W.
