From George Washington, First President of the United States, Farewell Address, (1796):
In the execution of such a plan, nothing is more essential, than that permanent, inveterate antipathies against particular Nations, and passionate attachments for others, should be excluded; and that, in place of them, just and amicable feelings towards all should be cultivated. The Nation, which indulges towards another an habitual hatred, or an habitual fondness, is in some degree a slave. It is a slave to its animosity or to its affection, either of which is sufficient to lead it astray from its duty and its interest. Antipathy in one nation against another disposes each more readily to offer insult and injury, to lay hold of slight causes of umbrage, and to be haughty and intractable, when accidental or trifling occasions of dispute occur. Hence frequent collisions, obstinate, envenomed, and bloody contests. The Nation, prompted by ill-will and resentment, sometimes impels to war the Government, contrary to the best calculations of policy. The Government sometimes participates in the national propensity, and adopts through passion what reason would reject; at other times, it makes the animosity of the nation subservient to projects of hostility instigated by pride, ambition, and other sinister and pernicious motives. The peace often, sometimes perhaps the liberty, of Nations has been the victim.
So likewise, a passionate attachment of one Nation for another produces a variety of evils. Sympathy for the favorite Nation, facilitating the illusion of an imaginary common interest, in cases where no real common interest exists, and infusing into one the enmities of the other, betrays the former into a participation in the quarrels and wars of the latter, without adequate inducement or justification. It leads also to concessions to the favorite Nation of privileges denied to others, which is apt doubly to injure the Nation making the concessions; by unnecessarily parting with what ought to have been retained; and by exciting jealousy, ill-will, and a disposition to retaliate, in the parties from whom equal privileges are withheld. And it gives to ambitious, corrupted, or deluded citizens, (who devote themselves to the favorite nation,) facility to betray or sacrifice the interests of their own country, without odium, sometimes even with popularity; gilding, with the appearances of a virtuous sense of obligation, a commendable deference for public opinion, or a laudable zeal for public good, the base or foolish compliances of ambition, corruption, or infatuation.
As avenues to foreign influence in innumerable ways, such attachments are particularly alarming to the truly enlightened and independent Patriot. How many opportunities do they afford to tamper with domestic factions, to practise the arts of seduction, to mislead public opinion, to influence or awe the Public Councils! Such an attachment of a small or weak, towards a great and powerful nation, dooms the former to be the satellite of the latter.
Against the insidious wiles of foreign influence (I conjure you to believe me, fellow-citizens,) the jealousy of a free people ought to be constantly awake; since history and experience prove, that foreign influence is one of the most baneful foes of Republican Government. But that jealousy, to be useful, must be impartial; else it becomes the instrument of the very influence to be avoided, instead of a defence against it. Excessive partiality for one foreign nation, and excessive dislike of another, cause those whom they actuate to see danger only on one side, and serve to veil and even second the arts of influence on the other. Real patriots, who may resist the intrigues of the favorite, are liable to become suspected and odious; while its tools and dupes usurp the applause and confidence of the people, to surrender their interests.
The great rule of conduct for us, in regard to foreign nations, is, in extending our commercial relations, to have with them as little political connexion as possible. So far as we have already formed engagements, let them be fulfilled with perfect good faith. Here let us stop.
