Do not forget that Obama had an unsanctioned, unvetted, unsupervised, "kill list" of people all over the world which he constructed and implemented entirely 'on his own' with no input or guidance from intelligence agencies or officials. This was during the "Arab Spring" period when Obama was casually dropping drones all over the world conducting executions of specific people completely on his own with no oversight.
Even today, we do not know who was on Obama's kill-list or how he obtained it. We do know that these killings and executions came with sometimes massive collateral damage (Obama bombed a wedding to kill someone on his list). We know that these killings were done surreptitiously and extrajudicially.
The worry is that Obama was taking 'orders' from his Muslim brothers for which he has strong fealty, or possibly other individuals to kill people who they considered to be an annoyance. That is, any Muslim involved the the Arab Spring could contact Obama through backchannels or somehow, and tell him "Omar such and such" is giving me a hard time, can you deal with it? Since there was no oversight at all from anybody, Obama could kill anyone on Earth for any reason or for no reason at all.
Obama is quoted to have said at a dinner party, "I am really good at killing people." Obama gave Iran top-secret American drone technology by landing a super-secret prototype stealth drone on an Iranian runway. Obama worked through his 'entire' administration (including the four years of Biden) to weaken America in any and every way possible, financially, militarily, and as a cohesive society. Obama was a destructor, who with his adopted 'mommy' Valarie Jarrett(Iranian) worked to diminish American power while working to empower his 'brothers' in Iran, Egypt, and the Muslims living in Israel.
Obama said that it is fundamentally 'not fair' that America should have so much wealth and power while his people (Muslims) live in poverty. His goal was to do whatever needed to be done to 'fix' this disparity.
