Canada and any of the provinces thereof, providing for mutual military
aid, and matters incidental thereto, in case of invasion or other
hostile action, disaster, insurrection, or imminent danger thereof.

provisions for joint military action against a common enemy; for the
protection of bridges, tunnels, ferries, pipelines, communication
facilities and other vital installations, plants and facilities; for the
military support of civil defense agencies; for the fresh pursuit, by
the organized militia or military forces or any part thereof of a

acting or appearing to act in the interest of any enemy government or
seeking or appearing to seek to overthrow the government of the United
States or of any signatory; for the powers, duties, rights, privileges
and immunities of the members of the organized militia or military
forces of any signatory while so engaged outside their own jurisdiction;
for such other matters as are of a military nature, or incidental
thereto, and which the governor may deem necessary or proper to promote
the health, safety and welfare of the people of this state; for the
allocation of all costs and expenses arising from the planning and
operation of such agreements or compacts.

governor to enter into, and to amend or supplement, such compacts, with
legal force and effect and without the legislative authorization
expressed herein.
