It's strange that Americans owe their country's existence to colonialism but are so prejudiced against it.
Other people's colonialism, that is. They have their own colonial empire. Puerto Rico, Hawaii, Alaska, various islands, Cuba and the Philippines in the past, Europe west of Russia.
All the USA east of the original 13 colonies is the result of American colonialism, I suppose. Including the lands taken from Mexico, that the Mexicans are now reoccupying.
AJP Taylor, the greatest 20th century British historian said:
“If the Germans had succeeded in exterminating their Slav neighbors as the Anglo-Saxons in North America succeeded in exterminating the Indians, the effect would have been what it has been on the Americans: the Germans would have become advocates of brotherly love and international reconciliation."He might have added that they would have disapproved of colonialism.
The US gets angry when Putin wants a sphere of influence in Ukraine and 'the near abroad', but the Monroe Doctrine delimits the US's sphere of influence (to include the whole Western hemisphere). This justified the Bay of Pigs invasion, for example, and the US embargo on Cuba.
Note how Eisenhower reacted over Suez (because of anti-colonialism) with Great Britain's support for him over Cuba.
I am not opposed to the Bay of Pigs invasion or the British attempt to land a force of émigrés in Albania to overthrow the Communists there. (Kim Philby ensured that didn’t work.) I just note American inconsistency.
