Mines are NOT “deterrent”. Strong army? Yes. Nuclear weapons? Yes. Mines are a minor nuisance during the war. Makes things uncomfortable, might slow down enemy movement a bit but that’s it. You can’t say to the potential enemy “Forget about attacking – we have mines near the border”.
“Intended recipient” doesn’t deserve to be notified. Unless you’re talking about Sweden, but I somehow doubt that :)
Yes they do. This is a deterrent, not a last-ditch effort to protect ourselves if war breaks out.

Saying "you won’t get anything of value quickly is a deterrent.
Security doesn’t need to be able to completely stop an enemy. It just needs to make it not worth the effort
