Obama was the first to use drone strikes to kill an American citizen without due process, and claimed that judicial process wasn’t needed since he was on foreign soil. You can read more about the al-Awlaki killing here if you want, this article lays out the case for how Obama escalated beyond what even GW did in the initial years of the war on terror for abusing the executive power to murder perceived political dissidents who were American citizens.

In the lead up to this, I believe what you’re referring to is the infamous wedding party strike. Dozens of Afghani civilians slaughtered while attending a wedding, because the US claimed there were Taliban insurgents present. Gee, where have we seen that line of reasoning in recent times? Oh yeah, similar excuse Netanyahu has used to completely level Gaza with the help of America. I’m not saying Obama was necessarily genocidal, but I also strongly rebuke his legal argument for these drone strikes resulting in extrajudicial killings as I believe it set a terrible precedent which we are suffering from at home today.
