Thank you.

To determine which agencies had the biggest impact on global transportation security post 9/11, we can consider their roles and responsibilities in this domain. Here's an explanation of each agency and its involvement in transportation security:

1. TSA (Transportation Security Administration): TSA was created in response to the 9/11 attacks. It is responsible for securing and screening passengers, baggage, and cargo at airports across the United States. TSA implemented various measures, such as thorough passenger screening, enhanced baggage screening, and the deployment of federal air marshals to ensure aviation security.

2. FEMA (Federal Emergency Management Agency): While FEMA primarily focuses on emergency management and response to disasters, it plays a vital role in transportation security post 9/11. FEMA collaborates with other agencies to develop emergency response plans, improve the resilience of transportation infrastructures, and coordinate integrated emergency management systems.

3. USCIS (United States Citizenship and Immigration Services): USCIS is mainly responsible for processing immigration and naturalization services. Although not directly involved in transportation security, USCIS plays a role in conducting background checks, vetting processes, and issuing visas for individuals traveling to the United States. These procedures contribute to the overall security of the transportation system.

4. CBP (U.S. Customs and Border Protection): CBP is responsible for securing U.S. borders and facilitating legitimate trade and travel. It monitors and inspects cargo and people entering and exiting the United States, both at airports and other ports of entry. CBP plays a crucial role in detecting and preventing the entry of unauthorized individuals, illegal goods, and potential threats to transportation security.

5. DOJ (U.S. Department of Justice): The DOJ encompasses various agencies, such as the FBI (Federal Bureau of Investigation) and the ATF (Bureau of Alcohol, Tobacco, Firearms, and Explosives), that are involved in counterterrorism efforts and law enforcement. Their focus on investigating and prosecuting individuals and organizations involved in terrorism contributes to the overall security of the transportation system.

Considering their areas of responsibility, the agencies with the most significant impact on global transportation security post 9/11 are likely to be the TSA, CBP, and the DOJ. These agencies have focused on enhancing security measures, protecting borders, and preventing potential threats to transportation systems.
