Maybe. I mean, this is a judgment call, I can't really argue with your personal judgment on the matter. You certainly don't have to apologize for anything you don't feel responsible for, even if someone else thinks you are responsible and should apologize.

But. I've thought about this, as an American, in relation to our treatment of all kinds of people. We certainly weren't very nice to our own indigenous people, or the people that we brought here in chains, or even the poor who worked (and work) the factories and the mines and the mills and so on, allowing for the prosperity of everyone (ideally).

And this really doesn't have to reflect on you at all, but in my own judgment, I feel responsible for some of that. I certainly benefit from it, even if I belong to some of those groups of exploited people mentioned above. I freely take advantage of living in America, and I think that makes me somewhat responsible for what made America.

Now, I should also mention that I choose my allegiance to America freely, also, and that choice is based partly on my own judgment that I'd rather be responsible for America than any other nation. That may sound like a strange choice to some people, at least now while America, by dint of its sheer size and energy requirements, is causing a lot of imbalance in the world. But y'know what, I don't have to live here, yet I choose to, and I think that makes me responsible to the people that are harmed, and have been harmed, by that choice.

Not a terribly coherent post, I realize. Not a terribly coherent subject.
