Intervention by States and Private Groups in the Internal Affairs of Another State

Headnotes: 

It would appear to be a violation of international law relating to neutrality if a neutral state permits the launching of an attack by organized armed forces from within its borders, permits the passage of organized armed forces through its territory, or permits armed forces to be organized and trained for such purpose within its borders.

There would appear to be no violation of international law where a neutral state permits the mere provision of arms by private parties, even the stockpiling of arms, as long as they remain within the control of private groups rather than belligerent parties, or permits volunteers to be recruited, assembled, and perhaps even trained, so long as this does not approach the point of an organized military force.
