Homeland Security/Homeland Defense

Instructions
Drawing upon resource material provided and that discovered while conducting your own research, answer the following:
Fully describe the overall concepts of homeland security and homeland defense. Construct a response that provides the following related to both homeland security and homeland defense:

Primary missions, tasks, responsibilities, operations, etc. for:

Homeland Security and
Homeland Defense.

Highlight those areas that are shared between the two (what overlaps between HLS and HLD?)
Lastly, recommend a definition for homeland security.

Using the overarching themes of the National Security Strategy from 2017, provide your own recommendation for new National Strategy for Counterterrorism (it must be nested under the NSS according to the principle of strategic hierarchy). What key elements and focus areas would you suggest for the part of a new CT strategy that is domestic focused (homeland security, not overseas), and make sure to use the Ends, Ways, and Means strategy framework.
Note: You should be aware of the fact that “homeland security” is made up of much more than just DHS. That agency is only one part of a larger Homeland Security Enterprise that includes [DHS] Departmental leaders and components [the 7 field agencies including USCG, CBP, ICE, USSS, etc], state, local, tribal, territorial and private sector partners and others. Also remember there are many other essential federal agencies that play a role in HLS, such as the very important DOJ where the FBI is the lead agency for countering terrorism in the US (not DHS).
