My question is

Did they actually SAY that the Aggression that we Responded to
Never Happened
And
The reason we went in was
A Lie?

No.

It's just a thinly veiled attempt to revitalize the chest thumping patriotism that supports illegal, immoral, unjustified military aggression.

Nobody wants to explain exactly
How these wars use our military to
Protect our Freedoms.

Come on, explain How our Freedoms have been threatened and by whom.

I won't be holding my breath.

Whoever wasted their time drinking Burns' Eighteen Hours of
Kool-Aid got propagandized.

“…How these wars use our military to
Protect our Freedoms. …”

Here is my, ’Shot’, at it.

1775            = Most Defiantly
1776            = Most Defiantly
1785            = Most probably
1786            =  ?  (Maybe)
1791            =  Maybe
1798 / 1801 / 1811, = NO
1812            = Yea  Defiantly
Next 8      =  Mostly,  ‘Indian Wars’
1838            = Yea
1846            = Yea Defiantly
Next 14    = Mostly Indian wars
1861            =  (You decide, if you tear down Statues, of that event)
Next 29      = Mostly Indian
1910      = Yea
Next 6  to the, ‘Great War’, No
The  Great  War = Most Defiantly
Next 2      = No
1941            = Most Defiantly
Next 25, to the present.  =  NO
  (Just the opportunity, for the $2,000.00 Hammer)

So the 25 after  WWll,  If this Nation held a, ‘Isolation’ view,
  Totality Not Necessary.
 If they did Not, hold a, ‘Isolationist’, view.  
Then they may have some Merit.
 
All Except  V.N.  That, was a  Total  Joke.
In 2-3 years, ‘COULD’, have  Completely done it.
 (But was, NOT, Allowed to)

Finally finished last episode. Overall, I'd say this was a fair look back at Vietnam. It's always hard looking back on major events because hindsight vision can't transport you back in time when the events were real. It's easy to say we should have never gotten involved. If North Vietnam overran South Vietnam in a matter of weeks or months in the early 60's, then who's to say what would have happened afterwards? That's an interesting argument, but I don't have the background for it. Vietnam was closer to my age but I know far more about WWII than Vietnam.

No one came out looking particularly well except the kids who were forced to fight. There was even arguments explaining how war crimes occur in all wars, but in this one, the situation made it inevitable that now only would they happen, but they would be more visible to the public.

Jane Fonda was rightfully torched. As was John Kerry. Nixon was rightfully crucified as well.  don't remember who it was but someone presented a case that of the 3 Presidents involved in this mess. JFK, LBJ and Nixon, it was Nixon who got the most "value" for the lives lost.
