"That keeping the agreement of peace, I can undertake productive works of considerable importance and destroy at the same time those of my enemy; or apart from enjoying the results of my own works, I shall also enjoy those of my enemy in virtue of the agreement of peace; or I can destroy the works of my enemy by employing spies and other secret means; or by holding out such inducements as a happy dwelling, rewards, remission of taxes, little work and large profits and wages, I can empty my enemy's country of its population, with which he has been able to carry his own works; or being allied with a king of considerable power, my enemy will have his own works destroyed; or I can prolong my enemy's hostility with another king whose threats have driven my enemy to seek my protection; or being allied with me, my enemy can harass the country of another king who hates me; or oppressed by another king, the subjects of my enemy will immigrate into my country, and I can, therefore, achieve the results of my own works very easily; or being in a precarious condition due to the destruction of his works, my enemy will not be so powerful as to attack me; or by exploiting my own resources in alliance with any two (friendly) kings, I can augment my resources; or if a Circle of States is formed by my enemy as one of its members, I can divide them and combine with the others; or by threats or favour, I can catch hold of my enemy, and when he desires to be a member of my own Circle of States, I can make him incur the displeasure of the other members. and fall a victim to their own fury,"--if a king thinks thus, then he may increase his resources by keeping peace.
