Answer:
The phrase which most clearly shows an imperialistic attitude is, 'we ultimately became.'
Explanation:
When we say that a country is having an imperialistic attitude, it means that it is trying to enlarge and widen its influence both in terms of geography and politics. Imperialism simply means to grow stronger, and this is mostly done by acquiring/gaining power over weaker and poor countries.
The statement, ‘and we ultimately became’ shows the imperialist attitude where the word ‘ultimately’ tries to depict the fact that finally, in the end we became an imperial power.
