Here is a thread I posted some time ago about where the term 'homeland' came from:
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=364x743946Initially, defense officials dubbed the overall program "homeland
defense," then acknowledge this could create a misperception of an
implied military takeover, Berkowsky said. Defense officials recently
changed the program name to "civil support" which "conveys much more of
the role that we legitimately have in this regard," she said.
This was back in the 90's the govt doc referencing this is here:

RAND Corp, 1999:
This report addresses the many conceptual, programmatic, and
practical issues associated with an emergent mission area for the
U.S. Army and Department of Defense (DoD) called “homeland
security” (until recently the mission was known as “homeland
defense”).At the most basic level, the report seeks to provide Army and other
DoD audiences with an introduction to, and overview of, four of the
five homeland security task areas,1 and the various organizations at
the federal, state, and local level that the Army and DoD may need to
interface with under different circumstances. More ambitiously, it
seeks to define homeland security in a concrete way and to provide
the necessary background and conceptual and analytic constructs
for wrestling with the key issues and choices the Army will face as the
mission area matures.
The research reported here was initiated as homeland security was
emerging as an issue of policy concern and was conducted during
Fiscal Year 1999, a year in which the Army and Department of
Defense considered but had not yet resolved many key homeland
security–related issues. These include a definition of homeland
security, the key task areas that constitute homeland security, and
the programs and capabilities needed to respond to these various
threats. In a similar vein, the broader federal government enacted or

THE CONSTITUTIONAL AND LEGAL CONTEXT
The fundamental justification and broader context for homeland
security activities can be found in the Preamble; Article I, Section 8;
and Article IV, Section 4, of the Constitution of the United States.
The Preamble includes the basic “insure domestic tranquility” and
“provide for the common defense” justifications:
Order to form a more perfect Union, establish Justice, insure
domestic Tranquility, provide for the common defense, promote
the general Welfare, and secure the Blessings of Liberty to ourselves
and our Posterity.
Article I, Section 8, elaborates on the circumstances in which the
military might be domestically employed:
Congress shall have Power . . . to provide for calling forth the Militia
to execute the Laws of the Union, suppress Insurrections, and repel
Invasions.
And Article IV, Section 4, expands on this authority:
The United States shall guarantee to every State in this Union a
Republican Form of Government, and shall protect each of them . . .
against domestic Violence.
Federal laws provide the specific mechanisms for federal (including
military) support to civil authorities, particularly in the context of
“civil emergencies”:
The modern authorization for Federal support to civil authorities is
based on the Robert T. Stafford Disaster Relief and Emergency
Assistance Act (P.L. 93-288) and the Economy Act. The former
enables the Federal Government to “provide assistance to U.S.
states, territories, and possessions to alleviate suffering and mitigate
damage resulting from major disasters and civil emergencies.” The
latter empowers Federal agencies to provide routine support to
each other under certain conditions if reimbursed. (Grange and
Johnson, 1997.)
Homeland security activities are even more apparent in the warrant
given the Department of Defense (DoD):
