Nope. And you are way off, first he calles it reenactment and after its показуха. By your logic every military expo is pokazuha, its not. Just because to show=показывать does not means it показуха.
So you dont know, but maybe this maybe that?ПОКАЗУХА "pokazukha" means the show, pretending to be cool for lames, so to say.
Or maybe when some general comes to visit the regiment and they begin to prepare in advance, so when he actually comes everything seems to be nice&cool. But in the fact...well, you know.
And other stuff like this. The show just for show. Cool picture but just a picture. Pokazukha ))
Show is better, pokazuha is a live show with kids, women , reporters or generals. Its to impress someone.
This is a good example of it. A picture of guys with weapons is not pokazuha.
