DANGEROUS POWER.
All nations may join."It is still easier to prove, that, should this formidable power betray any unjust and ambitious dispositions by doing the least injustice to another, every nation may avail themselves of the occasion, and join their forces to those of the party injured, in order to reduce that ambitious power, and disable it from so easily oppressing its neighbors, or keeping them in continual awe and fear. For an injury gives a nation a right to provide for its future safety by taking away from the violator the means of oppression. It is lawful, and even praiseworthy, to assist those who are oppressed, or unjustly attacked."—Book III. ch. iii. § 45.
