BODY POLITIC, the representation of a nation as a living or dead organism's body. Usually the metaphorical corpus is human, but other forms may be more appropriate in a given case, such as bovine, octopoid, or amoebic.
Describing a country's people as a body politic is convenient, as it allows for not only simple generalizations such as "the Enemy," but also increasingly complex divisions such as hindquarters, flanks and filets.
In the same way, a body politic can be described in terms of general national health as well as specific injuries, growths, obstructions, or even infections at the cellular level.
