On one hand you wish they were never created. On the other without the MAD(Mutually Assured Destruction) policy the cold war might have turned hot at some point and who knows what kind of world we'd have today. A conventional world war some time during the 70s for example wouldn't have destroyed the planet's ecosystem, but it sure would have costed many young men's lives. Whoever won we'd still be feeling the consequences today.

For small countries like mine overshadowed by big aggressive neighbors they are the perfect deterrent against being bullied by the bigger guy. Much like the threat of Izrael's supposed nuclear arsenal is there to scare off their big and powerful Arab neighbors.
