why was the department of homeland security created? answer

The Department of Homeland Security (DHS) was created in response to the terrorist attacks of September 11, 2001, which highlighted significant weaknesses in coordination and intelligence sharing among U.S. government agencies. The DHS was established by the Homeland Security Act of 2002, signed into law by President George W. Bush on November 25, 2002, to consolidate multiple federal agencies related to national security into a single cabinet- level department. Its primary mission is to secure the United States from terrorist threats or attacks and to improve coordination, preparedness, and response capabilities for protecting the homeland from a variety of hazards, including terrorism, natural disasters, and other emergencies. The department officially began operations in 2003, uniting 22 agencies under one umbrella to better protect the nation and its citizens.
