distinction between limited and unlimited war does not rest alone on the
moral factor. A war may be limited not only because the importance of the

WARS OF INTERVENTION--
LIMITED INTERFERENCE IN UNLIMITED WAR

* * * * *

Before leaving the general consideration of limited war, we have still to
deal with a form of it that has not yet been mentioned. Clausewitz gave it
provisionally the name of "War limited by contingent," and could find no
place for it in his system. It appeared to him to differ essentially from
war limited by its political object, or as Jomini put it, war with a
territorial object. Yet it had to be taken into account and explained, if
only for the part it had played in European history.

For us it calls for the most careful examination, not only because it
baffled the great German strategist to reconcile it with his theory of war,
but also because it is the form in which Great Britain most successfully
demonstrated the potentiality for direct continental interference of a
