I’m not sure either of these events can even be counted as an attack. Pearl Harbour is roughly 3800km from the mainland. It’s basically an overseas territory. An attack there is like saying the Falkland War was an attack on the UK.
And 9/11 was a terrorist attack, not a war. While it was a big attack, it was still only carried out by a handful of non-state-actors. That’s quite a different thing than an actual military attack by a country.

Afaik, the last war on US soil was the civil war.
