Considering where I live I've taken to pondering Ancient China too, and early Republican China. Dr. Sun's vision was glorious and I wish it could have taken root unpolluted by militarism and totalitarianism.
I'm torn on the nationalism. Dr. Sun's nationalism was undoubtedly a positive form of nationalism, a countermeasure to imperialism and a healthy attitude of "help yourself before you help others" that does not reject internationalism or exclude anyone from the nation-building.
And yet, see how it is twisted today to unite citizens against foreign specters and excuse expansionist policy and bullying of smaller neighbors.
