No European nation has tried to colonize any territory over which the independent country of the United States had ever laid claim. However, England, France, Spain, Netherlands, Sweden, Denmark, Russia, and Germany are all European countries that all colonized territories that have since become part of the United States.
All of the European nations are represented by sovereign powers. Each of the powers represent a different country. They have tried to make a European union resembling the US system and failed.
The US tried to help European nations that were devastated by World War 1 in various ways. There was so much money spent by the US government to help in rebuilding this nations and stabilizing their economies.
President Woodrow Wilson tried to get Congress to approve the US entry into the League of Nations. The League of Nations was the predecessor to the United Nations.
They received little respect from the European nations.

In return, the US will not involve itself in the internal affairs of European nations. The Spanish-American War (1896) bespoke the desire of the US to engage in expansion of its economic hegemony. From 1903 onwards, the the US conducted 'Dollar Diplomacy' to protect US companies' interests in Latin America.
