Answer:
an organization chartered by act of the U.S
Step-by-step explanation:
The Department of Homeland Security (DHS) is the national organization in America that has done the most to defend against acts of terror. This is determined by the fact that DHS was created after the 9/11 attacks to lead a unified national effort to secure America against terrorism. DHS is responsible for protecting the country from both domestic and foreign threats, including cybersecurity attacks, natural disasters, and terrorism. The department works closely with federal, state, and local partners to coordinate and implement initiatives to prevent, protect against, and respond to terrorist acts.
