It's because of the cognitive disconnect many have, with the constant praises of Obama in spite of actions like this.
Exactly, dude. Like imagine seeing people praising Obama and loving his wholesome little videos and I bring up the point that, hey, this guy got people blown to little pieces why do we still like him and the response I get is "oh, here we go again, somebody has to bring up the blown up people again". Like, surely someone else can see how fucked up that is right. Like you're really tired of people mentioning this dude got people killed. What an inconvenience to your Obama meme thread.
Everybody fucking knows Trump is ten times worse. But not everyone seemingly wants to acknowledge Obama is complicit in the US' systemic bombing of other nations since the 1950s. We're just going to keep shrugging it off or say "hey, that's just what presidents have to do". $90 million spent to help Laos remove bombs that
still haven't detonated yet after the US made the country the most bombed country in human history doesn't mean jack shit when you're simultaneously blowing up people elsewhere.
Americans are truly in a bubble when it comes to how fucked up US foreign policy is. Your precious presidents are all terrible. Your party politics whataboutisms are beneath me. Already got enough Trump cultists doing that to excuse every terrible thing he does.
