At least the Soviet atleast actually helped us during the second sino japanese war even if it wasn't out of the kindness of their hearts. Unlike the west which Jiang Jieshi sacrificed his elite soldiers to gain support from but we now know there were helping Japan behind the scenes.
I think the moral of the story here is that in a world where nations only have interests rather than friends, weak nations such as what China was in the 19th and early 20th centuries are only presented with two options. Which is either to be straight up oppressed or to serve someone else's interests for better or worse, with the better part rarely coming from altruism.
You want your nation's destiny to be more than than the sum of either of those two outcomes? Then make your nation strong. The rest is history.
Not that it really matters. Any Chinese family offshoots that stay in the West for more than a couple of generations turn into white washed hanjian anyways. The ones that stay in China will remain safe. The ones that have disowned their heritage or who have been disowned will be subject to hate crimes and racially motivated violence.
In light of discussions on the matter of loyalty recently, I will say that its not really a case of acknowledging your heritage but more so simply,
knowing right from wrong. When it comes to heritage, there is no two ways about it, all ABCs are going to be caught between two sides. Hated as "ch-nks" by the whites, yes. But be that as it may, they all grew up as Americans their whole lives. However hard they try to study Chinese culture, their knowledge of it will only be watered down versions of it compared to those who memorized thousands of Tang poems against their will. However good their Chinese gets, their accents will be off and their knowledge of slang terms commonplace to every Mainlander will be lacking. Heritage, roots, these are not exactly terms to apply to a people perpetually stuck in limbo whether they like it or not.
However, they still have the capacity to make choices. And with respect to the right or wrong choice here, its not a philosophical question in the slightest. It really boils down to, which do you think would give your children or descendants who look like you, a better future? The imperialist monster who wants to keep its boot heel on every nation populated by people who look like you? Where the public opinion is moving from boot heel to straight up extermination? Where whatever comforts you enjoy are from expedience rather than altruism? Or the nation that through thick and thin can finally usher in a world where people who look like you can stand tall? Perhaps you missed the bus through no fault of your own and can't do anything to change it, since that's just life sometimes. But that doesn't mean you can't do your part to make sure generations following you get on that damn bus and never look back.
