During Iran-Iraq war Islamic republic of Iran used brainwashing techniques and methods on mass population to get them to the war. Many kids have gone to that war only to act as a human suicide machine.
Although Islamic Iran's death toll during war was something between 500,000 to 1 million people but they were happy from the outcome. The Iranian government-owned Etelaat newspaper wrote:
"There is not a single school or town that is excluded from the happiness of 'holy defence' of the nation, from drinking the exquisite elixir of martyrdom, or from the sweet death of the martyr, who dies in order to live forever in paradise."Through Iran-Iraq war has been over for a long time but Islamic revolutionary Iran didn't stop indoctrination yet. Basij militia members and revolutionary guards go through some of the very same suicidal brainwashing techniques that you mentioned in above video. They are producing next generation of lambs for their Islamic revolution ideology.
