This week you learned that, although homeland security is a relatively new term, the U.S. has faced a variety of existential threats to its domestic safety and security over the past 250-plus years.

Please answer the following three-part discussion question in no more than three paragraphs:

• Briefly describe an incident from American history that, if it occurred today, would fall within the purview of the Department of Homeland Security and its component agencies.
• Specify the government functions (e.g. disaster management, migration, etc.) that were impacted and identify which government agencies provided a response to the event at the time of its occurrence.
• Finally, name the DHS components that would be involved in the present day.
