Why do you think that Trump didn't get any approval for killing the leader of ISIS?
I assume you are referring to how the US military kills the leader of ISIS and yet Trump is getting booed at a baseball game?
This is actually a pretty complicated question but two disclaimers
Firstly, quite a few leftist/centrist cites have been like “ok you did one good thing
Secondly, Fox news didn’t exactly give Obama credit for killing Bin Laden
Ok but unto the actual reasons
1) While Abu Bakr al Baghdadi/ “Caliph Ibrahmin” as he liked to call himself was an absolute shit head and deserved to die, he didn’t really hold the same role in the US discourse as Bin Laden. Like I don’t know how many Americans even would know his name if you asked two weeks ago, while everybody knew who Bin Laden was. ISIS was a threat, more as a group than its specific leader. this is also partly because while Bin Laden was the scion of one of the most powerful families in the world, Baghdadi was just a random farmer religious nut who got lukcy. There isn’t much known about Baghdadid compared to Bin Laden honestly. I mean his nickname was “The invisible sheikh” which is an odd choice for a “Caliph”
2) ISIS was mostly horrific to people in the middle east, while Bin Laden actually organized 9/11. That isn’t really fair, but many Americans viewed Bin Laden as a sort of Devil Figure and Baghdadi can’t really compete with that
3) The news was undercut by our stabbing the Kurds in the back and in the process accidentally releasing several hundred ISIS prisoners. So killing the leader doesn’t….really pay off for the massive destabilizing blow Trump had just dealt to the whole region for….apparently no reason?
4) Because of Trump’s life style and work ethic, if you aren’t already part of the Trump Cult, nobody really believes Trump played any role in the killing of Baghdadi? Like lets be honest here, the only reason why this operation happened is because Trump likely didn’t even know it was happening and then took credit after he was clued in like 2 days before the killing. A side effect of constantly golfing and publicly not knowing anything about your own policies means that people who don’t already love you don’t feel inclined to give you any credit.
This is doubled by the fact that Trump constantly lies, steals credit for other people’s work, and can’t be trusted. So even if there is a slight chance that he actually helped in this operation, nobody will believe him because his rep is ruined.
5) Also this is a natural effect of Trump’s combative politics, everybody knows that if the situation was reversed he wouldn’t be nice to us so why bother? Trump has destroyed any good feeling he might ever have, and once you ruin your credibility, then this is what happens
6) Its not like this is gonna actually stop ISIS, just like AQ stayed around after Bin Laden died. Its not that this doesn’t make any difference, but presenting it as a slam dunk when it clearly isn’t going to make the problem of ISIS go away is typical trump stupidity
7) Trump fucked up the delivery. By making the whole thing show like, it undercuts his own credibility. He presents it like a TV announcement, he talks about it as if it were an action movie, and he clearly is relishing in the violence he wouldn’t be able to inflict himself, so nobody really feels inclined to take him seriously except for the Trumpers themselves. Obama presenting it as a serious solome occasion, so people took it seriously. Trump treated it like a joke so did everybody else.
Ultimately though, this is really a lesson in politics, specifically what happens when you are deeply unpopular. The fact of the matter is if somebody is widely disliked, people don’t want to give them credit. Lets pretend for the sake of argument that Trump worked really hard on military intelligence and played a critical role in the killing of Baghdadi, it doesn’t really matter because...he is massively unpopular and didn’t win the popular vote. And part of the reason why he is massively unpopular is because he always hits below the belt, so it really isn’t any surprise that he isn’t being given too much credit for this, most of the country doesn’t trust him or like him enough to believe that he really helped play a role in the killing so they don’t feel inclined to be nice to him. Trump can’t really fix this, because this is the direct result of how he treats his fellow countrymen for the last 5 years, it is no surprise nobody wants to be nice to him now.
