You mean the war where America killed two million people based entirely on lies? That war?

What exactly did any Vietnamese to any American before they were invaded? (Did you know that Vietnam is still paying the US reparations for that war?)

No "propaganda" is needed - the United States own words and actions during that war tell the story of a morally bankrupt country that considers the deaths of foreigners to be meaningless.

Since WW2, the history of the US military has been one genocide after another.
