It's not. Instead of trying to come up with convoluted analogies for my conclusion to try and paint it as outlandish, maybe go back to talking about off topic stuff like BRICS.
It's not even close. You're comparing a time sensitive attack with tons of security to 4 pipes sitting in the ocean. A lone attacker on a short time scale, versus a potential entire state backed demolitions team with tons of operational lead time. Stop with the bad faith arguments.
It is highly unlikely that A) the US with such lead time would fail to blow up all 4 pipes, and B) the US would bother when it had already handled the situation diplomatically.
