The most significant to me is that all the death destruction and suffering was all to further enrich some 5ish rich dudes. It is significant because this aspect of the west has not changed at all. Just look how our historians are happy to attribute such acts to countries(!???) Until we start attributing invasions to the people who wanted them, those who organized them and those who profited from them this wont change…
Since we're at it, can we stop this China vs West thingy, as if the world was binary, as if the only relevant comparison was between those two? I dunno what you mean by West, but you're probably thinking of anglo-saxon countries, in particular the UK and the USA. What you're talking about doesn't apply to other countries that would qualify as western (e.g. Greece, Slovenia, Portugal, maybe some parts of Latinamerica). Besides, most of the world isn't either China (or East Asia if you will) or the West (What's India, Bangladesh, Russia, Africa, etc?). Let's please just stop, the world has more shades than that :-)
