As we are witnessing yet another round of the death spiral of imperialism, I was reminded of Césaire's quote on the domestic consequences of being an imperial power, which sadly aged well.
It's my own translation from french, hopefully I kept it close to the original.

[Aimé Césaire, in his later years, has a serious and slightly sad look on his face]
No one colonizes innocently
Nor does anyone colonize with impunity
A nation that colonizes, that justifies colonization - therefore force - is already a sick civilization, a civilization that is morally diseased, which, irresistibly, from consequence to consequence, from denial to denial, calls forth its own Hitler, that is to say, its punishment. Colonization is the bridgehead of barbarism within a civilization from which, at any moment, the negation of civilization itself may emerge.
