While true about that 'hero' marketing, you can claim the same about literally any marketing campaign, or things like American Dream (TM).

How many teenagers looked with starry eyes into US military recruiting PR campaigns, then get send to Iraq / Afghanistan, and instead of glory and cool adventures that were promised they saw death of peers and civilians on massive scale, they became invaders for at best questionable causes, experienced huge human suffering and destruction... which at the end didn't achieve anything positive at all, neither for US nor for locals, massively in contrary. Heroes look very differently in hindsight.
