Why was the Transportation Security Administration created?

The Transportation Security Administration (TSA) was established in response to the 9/11 terrorist attacks, marking a significant shift in how the United States approached aviation security. Following the attacks, it became evident that the existing security measures were inadequate in preventing such catastrophic events. As a result, the TSA was created to enhance the security of the nation's transportation systems, particularly in aviation.

The formation of the TSA aimed to centralize and improve security operations, implement standardized procedures across all airports, and ensure effective screening of passengers and baggage. This response was driven by the urgent need to restore public confidence in air travel and to protect against future threats. Thus, the creation of the TSA is directly linked to the national security challenges posed by terrorism, making this the correct answer.

In contrast, economic regulation of airlines, labor disputes, and environmental compliance, while important issues in the aviation industry, were not the primary motivations behind the establishment of the TSA, allowing for a clear focus on enhancing security in the wake of 9/11.
