Look at the Iraq War, up to today some Americans still
think that they invaded Iraq because of 9/11 and Saddam has
WMDs.
That is due to lack of propaganda telling them the truth in the
mainstream media there.
Most TV networks in USA are too busy with local news to bother
with foreign affairs, so the americans are ignorant and also
uninformed.
Some like Foxnews like to spread right wing propaganda, so many
become misled.
That is why I say TV is not a good medium for news coverage.
