May I reiterate, however, it’s only an issue if you’re concerned about what sort of news coverage the general population of the United States is getting.
My point is this… with the exception of publicly funded news organisations such as PBR for example (which have a pretty small market presence) by far the majority of US news media is in the hands of private enterprise - and private enterprise means making a buck and NOT scaring your audience away.
Contrast this with Britain’s BBC, or Australia’s ABC. In those countries, you have rather sizeable TV and Radio networks which are funded out of the Federal Government coffers. Accordingly, the same sort of commercial pressures which exist in Commercial TV and Radio don’t exist - in particular, the innate pressure to choose which stories are newsworthy based on trying to avoid scaring away as much of your audience as possible.
I personally have the highest regard for the USA’s most famous newspapers - remarkable journalists and talented, honest people. However, within reason, newsprint tends to follow the lead shown by TV news - it’s wrong, I know, but it does. There’s a cyclical relationship there.
So, I believe the answer to the OP lays most of all in the fact that US media organisations are privately owned enterprises which have to consider such issues as not losing ratings. Hence, American interest stories tend to assume greater priority over other foreign stories. And besides, the USA is a big, high action place. THere’s almost always enough interesting shit going on WITHIN the USA to fill an entire 6:30 pm News bulletin without any troubles whatsoever.
I’m willing to wager, however, that if the USA had a Federally funded equivalent to the BBC, then the lay of the land would be entirely different.
What tends to happen in Britain, and Australia (and I suspect Canada as well) is that the editors of the national broadcasters can make editorial decisions which are free of commercial pressures - and in doing so - our commercial networks follow the lead as it were… partially out of good conscience, and partially because they don’t want to be seen to be losing credibility to the National Broadcasters.
The solution (it seems to me) would be for the USA to create a federally funded National Broadcasting network which has editorial freedom to report factually which CAN’T be abused as a mouthpiece for those in Executive power. It’s pretty easy to achieve if you lay out the Broadcaster’s charter the right way.
One thing’s for sure, it would certainly allow the citizens of the USA to be seen thru the eyes of the outside world far more so than is currently the case - which is no bad thing I rather think.
