What agenda?
Does supporting the troops consist entirely of writing letters and sending cookies. That's apathy. Seeing that they die is the truth. Why shroud the truth? GI-Government Issue. Not showing the truth supports a more heinous agenda IMO, that they don't matter and stats in print of their loss don't upset the taxpayers or potential enlistees.
We had video footage of death and dying in WW2 and Viet Nam. Artists drew it in the Revolutionary and Civil Wars. Death and maiming are facts of war. Where one decides to come down on policy doesn't change those facts.
Oh yeah... death and dying are a fact of war... And that is no secret; and it's not something which needs to be advertised or used as propaganda which serves the interests which that Marine was FIGHTING AGAINST!
Propaganda is a force multiplier... where it serves the enemy, that doesn't change.
American troops simply need to understand that MSM reporters are their enemy; and they need to treat them as such. When more reporters who go out on patrol with American troops don't come back, they'll be fewer reporters who are willing to travel to wars zones to report on American troops only to return home to betray them.
