It is not the mission of the United States to set right everything that is amiss all over the world, even if we have interests involved, or to take part in remodelling the government of some four hundred millions of people who deeply resent foreign interference with their affairs.

the principle of non-involvement

Explanation:

The non-intervention rule is a principle of international law that restricts the ability of outside nations to interfere with the internal affairs of another nation. At its core, the principle is a corollary to the right of territorial sovereignty possessed by each nation.

Explanation:

Josiah Quincy: China and Russia (1900)

When the Boxer Rebellion erupted against the presence of foreign nations on Chinese soil, England, France, Germany, Russia,

and the United States dispatched a rescue expedition (including 2,500 American troops) to protect their citizens living in China.

Fearing that some of the competing Western powers might take advantage of the volatile situation to seize Chinese territory,

Hay decided to expand America's commitment to China to include the preservation of Chinese territorial and administrative

integrity as well as commercial equality. He failed to realize the long-range significance of such a commitment. In 1900 Josiah

Quincy, formerly first assistant United States secretary of state, criticized Hay and McKinley for committing the United States

to policies it could not enforce.
