I'm not saying that the US should be stanning Saudi Arabia, but it seems inappropriate to hem and haw about what is and isn't an "act of war" when actual literal missiles blew up actual literal people.

And the issue is that cyber attacks _are_ real attacks. Power outages like you've seen in Egypt and Venezuela kill people. These cyber attacks destroyed missiles. The stuxnet attack did 10s to 100s of millions of dollars to a uranium production facility. To pretend that flipping a switch to launch a missile and and flipping a switch to launch a virus to destroy the same target is somehow different is a false dichotomy, and contrary to published US policy.
