Seems unlikely. The US has successfully engaged in much more difficult, intricate operations successfully in the past. Here the attacker didn't even have to worry about collateral damage.

A former Navy SEAL was interviewed and stated pipelines are what they called (IIRC) "friendly targets" — it doesn't take much explosive to take them out (I imagine their pressurization helps, but I don't have subject matter knowledge).

Exactly. It’s funny how the US war machine fanboys ascribe such perfection it, especially after its glaring failures all over the Middle East.
