'Released from foreign war, we would probably be plunged into all the misery of anarchy and intestine war. Can we suppose that the people of the south, would submit to having the seat of Empire at Philadelphia, or New England; or that the people oppressed by a change of government, contrasting their misery with their former happy state, would not invite Britain to reassume the sovereignty.” — James Chalmers, Plain Truth, 1776
If the one above is the argument, you might consider that the colonists did obtain independence from England. That by itself was something that Chalmers always thought to be impossible without serious repercussions. He used to say that in the case of achieving freedom, America would just end up being attacked and maybe even colonized by some other country. What happened, thought, was that after the revolution, other countries gained respect for America as an opponent and the country was eventually left to be.
One piece of evidence that Duara uses in the passage to support his claim regarding Western racial attitudes and Japanese militarism in the second paragraph is where he says that Japan was allotted a lower quota of ships than the British and Americans.
Or you can say...
Discrimination was perceived in the international conferences in Washington (1922), the London Naval Conference (1930), and wherever Japan was allotted a lower quota of ships than the British and Americans. But most of all, it was the buildup of exclusionary policies in the United States and the final Exclusion Laws prohibiting Japanese immigration in 1924 that galled Japanese nationalists. In their view, Asian civilization did not exhibit inhuman racist attitudes and policies of this kind, and for [Japanese] militants . . . these ingrained civilizational differences would have to be fought out in a final, righteous war of the East against the West.”
