Question

the great rule of conduct for us in regard to foreign nations is...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 europe 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 fluctuation or changes of her politics, or the ordinary combinations and collisions of her friendships or enmities...
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 ambition, rivalship, interest, humor or caprice impulse?
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 it, therefore, let those engagements be observed in their genuine sense. but, in my opinion, it is unnecessary and would be unwise to extend them.
why should the united states avoid \interweaving our destiny\ with europe, according to washington?
europe welcomes american mediation in its conflicts
european rivalries are largely unrelated to u.s concerns and could entangle american peace and prosperity
the u.s needs european protection to survive
the constitution forbids all treaties with foreign nations

Explanation:

The text states that Europe has primary interests that are unrelated to the U.S. (or very remote). Europe is engaged in frequent controversies whose causes are foreign to U.S. concerns. Interweaving destinies would entangle U.S. peace and prosperity in European rivalries (ambition, rivalry, etc.).

Answer:

European rivalries are largely unrelated to U.S concerns and could entangle American peace and prosperity.
