Understanding Homeland Security
Discussion Post
Prompt 1.
National security is the whole range of strategies and actions implemented by a nation-
state to safeguard its populace, territorial integrity, and vested interests against both domestic and
foreign hazards. The term "national security" refers to a comprehensive set of policies and
measures implemented to safeguard the welfare and protection of a country and its governing
body (Newsome & Jarmon, 2020). The preservation of the sovereignty and independence of the
United States, together with the development of military capabilities, information collection,
diplomatic endeavors, and economic stability, are among the critical components of national
security.
Conversely, the concept of international security is centered on the preservation of peace
and stability among nations at a global level. The concept encompasses the administration of
conflicts, the mitigation of armed conflicts, and the resolution of collective challenges that have
the potential to impact numerous nations (Newsome & Jarmon, 2020). The field of international
security encompasses the examination of the interdependence of states. It seeks to foster the
values of cooperation, collaboration, and mutual comprehension while discouraging the
utilization of force or aggression as a mechanism for dispute resolution.
The concept of homeland security primarily concerns safeguarding the United States
against internal hazards, encompassing both occurrences of natural calamities and acts of
terrorism. The task at hand encompasses the proactive measures and reactive actions taken to
mitigate potential harm to American residents, essential infrastructure, and the smooth operation
of society. According to Tanner & Beckner (2020), the field of homeland security centers on
effective coordination among diverse governmental entities, including the Department of

Prompt 2
The United States, Great Britain, and Canada exhibit distinct methodologies in the realm
of homeland security. The United States places significant importance on safeguarding its
borders, allocating substantial resources toward border security measures and immigration
regulations (Newsome & Jarmon, 2020). On the other hand, Great Britain prioritizes the
acquisition of intelligence and the dissemination of information to international counterparts as a
means to counteract terrorism. Canada places significant emphasis on fostering robust integration
and collaboration among diverse agencies and departments in order to guarantee a cohesive and
efficient approach to addressing potential risks (McIntyre, 2019). In addition, Canada
implements community-based strategies for homeland security, involving citizens in activities
related to prevention and emergency response. In contrast, the United States and the United
Kingdom mainly depend on professional agencies for these purposes.
Various variables, including historical events, national security considerations, and
cultural and political circumstances, have shaped the approach to homeland security in different
countries. The events of the 9/11 attacks have significantly influenced the approach of the United
States, while the approach of Great Britain has been shaped by the ongoing threat of domestic
terrorism (Newsome & Jarmon, 2020). Examining comparative examples of homeland security
is advantageous as it allows for the identification of optimal approaches, the acquisition of
knowledge from both successful and unsuccessful endeavors, and the promotion of international
collaboration in effectively tackling common security concerns.
