How did American cause Altair's in Vietnam affect public opinion back

Affairs in Vietnam affected the public pinion in US as it was the war that was extensively covered on TV

Explanation:

The Vietnam war was the first war that America fought that was covered by free press over TV who showed the common people the true horrors of the war they were witnessing and ended up influencing the public opinion against the government.

The public felt a disconnect from the war as they could not identify the reason why their soldiers were fighting so far away from home without a seemingly important cause to them at least as things back home seemed fine.
