Final answer:
In response to 9/11, facility managers saw the creation of the DHS and TSA, reflecting a shift to central federal power, with strategies focusing on security, federal mandates, and revised foreign policies to combat non-traditional terrorist threats.
Step-by-step explanation:
Post 9/11, facility managers and policymakers implemented several new strategies to enhance security and respond to the challenges of terrorism.
The establishment of the Department of Homeland Security (DHS) consolidated federal emergency response initiatives in Washington, centralizing efforts to protect the nation from various threats.
The creation of the Transportation Security Administration (TSA) was another major move, aimed to federalize airport security and improve screening processes to prevent similar attacks.
Extensive federal policies and mandates were enacted, with security and preparedness as central goals.
These strategies reflected a significant shift towards central federal power and a re-evaluation of foreign policy approaches to address non-traditional enemies, such as terrorist groups like al-Qaeda and ISIS that function beyond national borders.
Such changes also had domestic implications, including a new willingness to limit civil liberties and an increase in government trust.
