It's hard to remember all the strikes that Trump did but I doubt he did one this early.
Trump did exactly one strike, and that was in response to a gas attack in April 2017. Trump also ordered a drone strike to kill an Iranian general.
To be fair to Biden, Iranian forces (and proxy forces) have been attacking US troops and assets recently.
I'm assuming you mean largely public strikes? Not just a drone strike or something along those lines in general -- as the media reports that Donald Trumps drone strikes far exceeds Obama numbers
Still not sure what the fuck we're doing in all these other countries when our own people are suffering. But nothing changed under Trump and he was the one pushing that line of thought for a little while.
