Indeed. It was an attack on an Iraqi base, very large site so it’s actually unlikely to hit much of anything, with word of no American casualties. Good reason for Trump to not make a serious retaliation; it was a show for Iranian propaganda best followed up by sanctions further targeting Iranian leadership - not killing conscripts.
If anything, track the equipment and pulverize the home base. Yes we can escalate severely, but not over this.
If there’s no casualties, he could always get on Twitter and mock the vaunted Iranian war machine...
