Well, re:Iraq/Afghanistan, news of soldiers coming back in caskets very much contributed to Bush's unpopularity. At the end of the day, chanting "we're fighting for freedom! and democracy!" isn't enough to keep 'muricans in hawkish zeal. It popped the popular perception that pointy end of the military industrial complex was only for ~~brown people~~ non-americans. Which is why proxy wars are the go-to now, much more secure in support from the metropole.
edit: and less news of Americans dropping missiles on weddings
if you want general history, there's a relatively comprehensive docu-series produced by CCTV6 from 2013 called 中国通史 General History of China (100 episodes). However it's in Mandarin Chinese, so not very podcast-able if you don't understand Mandarin, but there are english subs available (on a quick search, and a brief glance they look decent) and IMO the artifacts and depictions are worth the watch. If anything it might be a good launching point if you wanted to look into more specific topics, for example, philosophy which is often intertwined with religion and civics in Chinese history, or historic literature.
EDIT: found an english dub on youtube ^^ just search "general history of china eng dub"
