One related point: Stuxnet only set back the Iranian nuclear program a few months at most, while endangering the security of nearly the entire internet in the process, as well as opening up a new weapon of war in the form of digital attacks on critical infrastructure.

The US even had to divert a ton of resources to secure its own systems, from itself (and Israel)'s attack. Its probably the worst case of blowback we have so far in the digital era.

The documentary zero days is really good, and goes over this.
