They had adhered to that instruction to a reasonable extent. The Monroe Address of 1823 was evidence of that as the United States government warned the European powers against interfering in the politics of the Western countries.
The reason for this was to avoid political interferences and meddling by these nations.
Step-by-step explanation:
At the early stages, the leaders did not heed Washington's advice because there were some who were pro-British and others who were pro-french. But by 1823 the United States had clearly defined their boundaries with these nations. In 1796, outgoing President Washington in his farewell address urged the United States leaders to avoid political alliances with European nations so that they do not meddle in their affairs. As of 1798-1800, there was a naval war between France and America because the French people believed that they had an agreement with Britain to seize their wares in return for money.
On June 18, 1812, there was a war between America and Britain that ended in a draw and sent a clear message to all nations that the Americans could defend their sovereignty. By 1823, a strong warning was given by the United States to the European nations to steer clear of their politics.
