However, trying to help you with something, we can comment on the following.
There are many questions like this that refer to the actions taken by the United States regarding expansionist and imperialistic ideas. If that is the case, then we can say the following.
Under the principle of the Manifested Destiny, the United States had taken interventionist or expansionist actions that have resulted in the increase of the size of its territory, by annexing big portions of land.
That was teh case of the Mexican-American War, in which after the US victory, it annexed California, Arizona, and New Mexico.
Another good example was teh Spanish-American War of 1898. After the war, the US victory gave the US control of territories that belonged to the Spanish crown. We are talking about Guam, Puerto Rico, and the Philippines.
For these kinds of actions, and new interventionist ones in the Middle East of Central American, the US has been severely criticized worldwide.
