I don't see how that is a Western moral, in fact modern Western mores are incredibly self-loathing about imperialism, in sharp contrast with say Japanese attitudes, just as a recent example. You suggest that non-Western cultures are less power grubbing. Which ones exactly? The Aztecs? The Mongols? The Japanese? The Zulu? The Arabs? The Persians? The Chinese? Power grubing is as universally human as speech.
