Federalist Papers 3C

It is of high importance to the peace of America that she observe the laws of nations towards all these powers, and to me it appears evident that this will be more perfectly and punctually done by one national government than it could be either by thirteen separate States or by three or four distinct confederacies.

Because when once an efficient national government is established, the best men in the country will not only consent to serve, but also will generally be appointed to manage it; for, although town or country, or other contracted influence, may place men in State assemblies, or senates, or courts of justice, or executive departments, yet more general and extensive reputation for talents and other qualifications will be necessary to recommend men to offices under the national government,--especially as it will have the widest field for choice, and never experience that want of proper persons which is not uncommon in some of the States. Hence, it will result that the administration, the political counsels, and the judicial decisions of the national government will be more wise, systematical, and judicious than those of individual States, and consequently more satisfactory with respect to other nations, as well as more SAFE with respect to us.
