Military school, a lecture on tactics. The teacher for one and a half hours talks about the organization of security and defense of the position of the unit. Discuss diversion and intelligence groups and methods of combating them. And suddenly he says:

- You know, in fact, these saboteurs are not so scary... Idiots in the leadership – that’s what is really scary. Well, the sabotage explodes the bridge, it is unpleasant, but it can be restored. An idiot is able to rebuild something that there is nothing to rebuild.

I thought here - the most disgusting thing, with the saboteurs I have not yet faced, but idiots meet regularly. It is a pity that no one has been taught to fight them.
