How does a war become popular?

Answer 1

Formerly, when books were written about them. Commencing with the latter part of the 20th century, when Hollywood made movies (films) about them. It should be noted however, that movies (films) are generally adapted from "books." Unfortunately, sometimes, Hollywood films act as a form of "marketing" for a subject. The word "unfortunately" is used because Hollywood OFTEN depicts un-correct/non-factual situations that lead audiences astray. Example 1: In movies, hand-grenades explode like balls of fire (audiences appear to enjoy those special effects); in reality, grenades explode into a ball of black smoke in the day time, and only show a small ball of fire at the base of the detonation during nightime (darkness). Example 2: In real life machineguns and automatic rifles empty within seconds (maybe 3 seconds for an 18 round M-16 rifle magazine, on full rock 'n roll). Hollywood M-16's fire seemingly hundreds of rounds before their magazines empty. Example 3: In real life when a man's shot he sometimes struggles on the ground for minutes before dying, and not normally making much noise, except trying to breath. Hollywood has the man dying almost instantly and/or making an awful lot of verbal communication before death over-takes him. Script writers are to blame, and the lack of non-politically correct military technical advisers.
