Apparently, USG is doing the same thing it did before the June attack on Iran.
Expect that if Iran shows restraint or is unable to hit back, the shills will say: "See? They're a paper tiger, and can't do anything. Let's bomb them more."
Expect that if Iran does hit back and kills any number of American soldiers, the shills will say: "Outrageous! They have killed Americans! Let's bomb them more."
No, they won't. They will pivot to outright supporting a ground invasion of Iran.
