Wiki gives a different impression of what Confucianism is

It seems like Confucius was ahead of his time actually. In fact, what you are describing seems more like the Machiavellianism of Renaissance Europe. A school of thought that is formed in the turmoil of Europe over the centuries prior.
China for large chunks of its history has been unified, and existed in a state of relative peace among its inhabitants. Whereas Europe, even till now, has always been fragmented. There has always been lots of competing powers. That creates the perfect environment to nurture the kinds of ideas, and notions you are attributing to the east asians. The chinese are what they are now largely because of the machinations of the CCP. A CCP whose founder, Mao, was a student of the west especially Classical Liberalism.
Well, you say Confucianism gives a "different impression," based on the Wikii and then have not said what the differences are or how the source would reach these conclusions.
Therefore, I can not fairly respond to your protests I'm afraid.
By the way, I would recommend "The Analects of Confucius: A Philosophical Translation" translated by Rogert T. Ames and Henry Rosment Jr. It captures a lot of the meaning, though the language is difficult because it tries to match the original Chinese and academic standards.
As for, the ruminations on the "peace" of unified China (I think Vietnam would differ in opinion, or the vassal states in Korea, or the invasions from the Mongols and Manchurian would differ. Isolation did not equal "peace" in the modern, American interpretation of the word ) if we assume this peace existed, hmm, what of the people who lived in the peaceful empire? As it a harmonious dream or contemptuous prison of filial slavery?
When you read about the slave labor worked to death on the Great Wall, one starts to understand a bit, the horrific cruelty of the empire, the ruling magistrate, or in the links of filial piety one might start to see deeper into why China's past is one of sorrow and outrage. That's just the chapter leading up to Maoism.
As well, to be honest you're not arguing otherwise, nor perhaps are arguing from an understanding of Chinese history, philosophy, personal experience, or it seems from an understanding of these ideas.
How knowledgeable are you personally?
Allow me ask a few simple questions:
How long have you studied Chinese history, philosophy, and principles?
How many times have you traveled to China or Hong Kong, Taiwan, Singapore, or the Far East?
Have you ever lived in any of these places?
How many Chinese people have you spoken to and discussed ideas with? Do you have any street knowledge to go with any possible book knowledge. Any Chinese friends with a high level of education?
How much do you understand about cultural theory in general, and about how theories like, oh, Power Distance, relate to Mainland ideas?
Have you ever lived in China?
How good are your Chinese language skills?
I would like to know, if you do not mind.
