Could go either way. U.S. infrastructure is terrible and getting worse, which is why the country is collapsing. but (IIRC) natural gas hookups aren't one of the issues that that report emphasizes.
If one building exploded due to a leak then clearly that points to decaying infrastructure, but if dozens of houses explode due to overpressure then that seems more ambiguous.
You're just changing infrastructure attack to industrial espionage. You calling it something else doesn't detract from the point that it's been done, and it was targeted at one country or another's infrastructure.
Nukes don't deter infrastructure attacks. They ENCOURAGE them. Cripple your opponents ability to maintain his arsenal and coordinate his forces, and you could shift the odds of pulling off a crippling first strike immensely.
I am genuinely terrified that there are apparently a number of people who share this attitude.
Here's hoping none of you are anywhere near the leavers of power because this is far more dangerous than garden variety doomsday delusions like Jesus returning, or ignoring climate change.
1). Blame 50 years of infrastructure neglect to the point that the US is ranked a D+ [0] in infrastructure.
2). Blame a country with the population of Nigeria, the GDP of Italy and the military spending of Suadi Arabia?
