Federalist Papers 5D

The North is generally the region of strength, and many local circumstances render it probable that the most Northern of the proposed confederacies would, at a period not very distant, be unquestionably more formidable than any of the others. No sooner would this become evident than the NORTHERN HIVE would excite the same ideas and sensations in the more southern parts of America which it formerly did in the southern parts of Europe. Nor does it appear to be a rash conjecture that its young swarms might often be tempted to gather honey in the more blooming fields and milder air of their luxurious and more delicate neighbors.

They who well consider the history of similar divisions and confederacies will find abundant reason to apprehend that those in contemplation would in no other sense be neighbors than as they would be borderers; that they would neither love nor trust one another, but on the contrary would be a prey to discord, jealousy, and mutual injuries; in short, that they would place us exactly in the situations in which some nations doubtless wish to see us, viz., FORMIDABLE ONLY TO EACH OTHER.

From these considerations it appears that those gentlemen are greatly mistaken who suppose that alliances offensive and defensive might be formed between these confederacies, and would produce that combination and union of wills of arms and of resources, which would be necessary to put and keep them in a formidable state of defense against foreign enemies.
