An excerpt from the Federalist Papers:
"But whatever may be our situation, whether firmly united under one national government, or split into a number of confederacies, certain it is, that foreign nations will know and view it exactly as it is, and they will act towards us accordingly. If they see that our national government is efficient and well administered ... our trade prudently regulated... our militia properly organized and disciplined... our resources and finances discreetly managed... our credit re-established ... our people free, contented and united, they will be much more disposed to cultivate our friendship, than to provoke our resentment. If, on the other hand, they find us either destitute of an effectual government, (each state doing right or wrong as to its rulers may seem convenient) or split into three or four independent and probably discordant republics or confederacies, one inclining to Britain, another to France, and a third to Spain, and perhaps played off against each other by the three, what a poor pitiful figure will America make in their eyes! How liable would she become not only to their contempt, but to their outrage; and how soon would dear bought experience proclaim, that when a people or family so divide, it never fails to be against themselves."
Let's go over it:
Is our national government efficient? No
Is our trade prudently regulated? No
Is our militia (military) properly organized and disciplined? This is open to debate, but the Obama administration's social engineering damage has made our military weaker.
Our resources and finances discretely managed: Nineteen trillion in the hole, which will never be paid back. No.
Verdict: "...what a poor pitiful figure will America make in their eyes"
We are already seeing the effects of that.
