External subversion is actions taken by another country in cooperation with those inside the subverted country and can be used as a tool of statecraft. Foreign volunteers from another country are not enough to qualify for external subversion. The reason for this is that the individuals may legitimately share the cause of the internal subversive dissidents and have legitimately volunteered. Only when the government itself furnishes a nation with money, arms, supplies, or other help to dissidents can it be called external subversion.
