"But if the Union, as has been shown, be essential to the security of the people of America against foreign danger; if it be essential to their security against contentions and wars among the different States; if it be essential to guard them against those violent and oppressive factions which embitter the blessings of liberty, and against those military establishments which must gradually poison its very fountain; if, in a word, the Union be essential to the happiness of the people of America, is it not preposterous, to urge as an objection to a government, without which the objects of the Union cannot be attained, that such a government may derogate from the importance of the governments of the individual States?"
- James Madison (Federalist Paper No. 45)
