I think you have a reading comprehension problem, but I don't think I'm capable of fixing it. Hint: it revolves around the word 'since'. Best of luck.

The poster claimed this was a "9/11 scale crisis", I think it is not.

Rather than engaging in the reasons for why it might be, you choose to insult my reading comprehension. Take care, and hopefully you can be more charitable to those you encounter in-person.

It literally says "the biggest attack on the US since 9/11" in your quote. And it was. That's the part you had a problem with.
