The very novelty of the rigid neutrality proclaimed by Washington made the policy a difficult one to pursue. In the Revolutionary and Napoleonic wars, which lasted for nearly a quarter of a century, the United States was the principal neutral. The problems to which this situation gave rise were so similar to the problems raised during the early years of the World War that many of the diplomatic notes prepared by Jefferson and Madison might, with a few changes of names and dates, be passed off as the correspondence of Wilson and Lansing. Washington's administration closed with the clouds of the European war still hanging heavy on the horizon. Under these circumstances he delivered his famous Farewell Address in which he said: "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_ connection as possible. So far as we have already formed engagements let them be fulfilled with perfect good faith. Here let us stop. "Europe has a set of primary interests which to us have none or a very remote relation. Hence she must be engaged in frequent controversies, the causes of which are essentially foreign to our concerns. Hence, therefore, it must be unwise in us to implicate ourselves by artificial ties in the ordinary vicissitudes of her politics or the ordinary combinations and collisions of her friendships or enmities. "Our detached and distant situation invites and enables us to pursue a different course. If we remain one people, under an efficient government, the period is not far off when we may defy material injury from external annoyance; when we may take such an attitude as will cause the neutrality we may at any time resolve upon to be scrupulously respected; when belligerent nations, under the impossibility of making acquisitions upon us, will not lightly hazard the giving us provocation; when we may choose peace or war, as our interest, guided by justice, shall counsel. "Why forego the advantages of so peculiar a situation? Why quit our own to stand upon foreign ground? Why, by interweaving our destiny with that of any part of Europe, entangle our peace and prosperity in the toils of European ambitions, rivalship, interest, humor, or caprice? "It is our true policy to steer clear of permanent alliances with any portion of the foreign world, so far, I mean, as we are now at liberty to do it; for let me not be understood as capable of patronizing infidelity to existing engagements. I hold the maxim no less applicable to public than to private affairs that honesty is always the best policy. I repeat, therefore, let those engagements be observed in their genuine sense. But in my opinion it is unnecessary and would be unwise to extend them. "Taking care always to keep ourselves by suitable establishments on a respectable defensive posture, we may safely trust to temporary alliances for extraordinary emergencies."
