Journalism in America has developed into a forum for Treason and Sedition. That has been obvious since the Korean War.
Well you could say the same thing about a very large number of journalists during the Revolutionary War (Royalists), the quasi-war with France (anti-Federalists), the War of 1812 (nearly all of New England, especially early in the war), the War with Mexico (lots of folks), and especially the Civil War (Copperheads), not to mention anti-imperalists during the Spanish-American war. Hostile reporters are not a new phenomenon.

Those earlier cases were different. The Civil War, for example, did not have Americans opting to turn the country over to the Barbary pirates. Both sides in the Civil War were fighting for home and country. That is much different from simply being on the enemy side.
We had rather few outright traitors in WWII, except for some communists working under cover in the FDR administration. Later on, things changed. Today, much of the media is on the other side, and are plainly anti-American.
You make several good points -- our challenges today are indeed different to what Americans faced in the past.
I was just trying to say that we shouldn't kid ourselves about some golden age in the past when the press supported the military and our military missions -- there are lots of examples from history where that wasn't true.
Overall, freepers sometimes seem to feel that our challenges today are especially difficult, and that people had it easier in a rosy past. I think just the opposite -- compared to the past, the present looks pretty rosy to me.
