Answer:
To keep European powers from interfering in American affairs
To keep American lands out of the hands of European powers
Explanation:
The excerpt is part of one of Jefferson's letters to American President Monroe, where he affirmed that allying with Britain in order to protect the Western Hemisphere, whose interests were distinct from those of Europe, from European powers would be highly beneficial to the US. With this in mind, in this part of the letter, Jefferson sets the main goals of the American system: to keep European powers from interfering in American affairs and to keep American lands out of the hands of European powers.
