Any system can be destroyed.
Even if it is a decentralized network of nodes that is controlled by noone and everyone at once.
Just turn off electricity all over the world, or the internet. If you mean hacking such a system, this is impossible.
This is the unique feature of the blockchain technology.

LoL. In the last part it was being stated that block chain could not be destroy. Hmmmm. I guess it could be.
