[antidisestablishment]

imperialism
noun
1. the policy of extending the rule or authority of an empire or nation over foreign countries, or of acquiring and holding colonies and dependencies.

Accepting a true definition of imperialism, there is no reasonable debate. If we truly “toppled them by force” in order to “impose our will,” why don’t these damn countries do what we want? Why am I still 7500 miles from my home?

Redefinition is the raison d’etre of Leftism. Calling good evil and evil good is the heart of the left.

It appears you forgot to mention the 2nd definition which seems to apply, I'm sure that was simply an oversight on your part.

1. the policy of extending the rule or authority of an empire or nation over foreign countries, or of acquiring and holding colonies and dependencies.

2. advocacy of imperial or sovereign interests over the interests of the dependent states.

Or we could look to Merriam-Webster since, as you pointed out, words have a precise meaning.

: a policy or practice by which a country increases its power by gaining control over other areas of the world

: the effect that a powerful country or group of countries has in changing or influencing the way people live in other, poorer countries

Imperialism was used correctly in this case.
