I came to know about the Marvel movie military involvement from a youtube video essayist. I don't know whether it's good or bad. It's somewhere in the middle probably. Also every other country does the exact same thing afaik. The opposite of this would be potraying everything about the armed forces in a complete negative light. Now that won't be liked a lot I guess. The important thing here I believe is people should learn to detect if something is a propaganda or not. And the problem now is that its very subtle. Most people with whom I have discussed already detect the blatant propaganda movies instantly. The subtler ones like the marvel movies are the ones which they are very suprised about.
