Probably true
Especially 'cause I gotta add something here as well, I don't think it's glorification of the past as much as it's a glorification of the present. By emphasising the death due to military activities, and at least on a subconscious level making it seem worse than dying of hunger, it's indeed possible to make the present situation seem much better than the past, while ignoring, or at least downplaying the suffering endured due to socioeconomic structures today.
This is not to say that there haven't been massive improvements in the fields of a lot of human rights and human welfare in general, and of course starvation and famines were commonplace in past times as well, but what my point really is is that future generations will look at the current disparities in terms of wealth, with excess in one part and hunger in the another with much less indifference than is currently done.
