Street signs, safe from invasion?

Seen recently on the lamp posts of my town, street signs indicated which street it is. In World war 2 Britain removed all of it’s sign posts to prevent the invading Germans from knowing where they were.

Could it be taken that a re-introduction of street signs means an easing of tension (between the North and South Koreas), or just that the local council has money left over and it’s nearing the end of the fiscal year?
