The problem with whataboutisms (other than being fallacious), is that you're basically admitting that you completely agree with that which you're trying to dispute by trying to deflect away from.
What does Biden and Covid vaccines have to do with Trump attacking Iran for actually no reason last year, claiming that he obliterated their nuclear development sites, only to attack them again for no reason now to obliterate those nuclear sites again which were obliterated.
Even if anything was salvageable in those sites from the first time around, they're somewhat on the radioactive side due to getting blown up. So no, it wasn't a matter of putting a door back on its hinges and opening it just to walk back in and rev up those centrifuges again.
