I’d recommend starting out by reading a very biased but well researched and factually correct book, which will give you invaluable information about how it all became the way it is today, which will make it possible for you to discern who lies about what and why today:

Well, most people in the world are not really quite that interested in what’s happening in the US, it’d be quite easy to miss something that doesn’t really have any repercussions abroad, like the opioid crisis.
