Christ. most of them.

George Washington got to be in charge of a country that enshrined chattel slavery in its constitution for 20 years. Thomas Jefferson provided military aid to France's efforts to quash a slave revolt in Haiti. Andrew Jackson personally orchestrated a genocide against the Cherokee, Creek, and Choctaw (all of whom were aligned with american interests). Zachary Taylor put a bounty on bison, in an effort to starve the native Americans of the great plains. Abraham Lincoln allowed his western military expeditions to do basically whatever to the native Americans. Andrew Johnson started the process of letting confederate leadership be who directed reconstruction rather than being punished for it.

And here we reach Ulysses S Grant. one of America's favorite punching bag presidents because he got scammed rather frequently, but when you dig into why he was prone to getting scammed, it's because he thought it was America's duty to use its economic power to help the lowest people in society. it's hard to be mad at a guy who was trying so hard to help people that sometimes he let someone con him into thinking they deserved help.

i can keep going on how a ton of our historical presidents have sucked. i'm still personally willing to say the top 3 are Andrew Jackson, Ronald Reagan, and Donald trump

Pretty much all of them actively participated in various genocides and massacres, either directly like native genocide or Philippines or all the aerial massacres of XX and XXI century (even the one who was president for a month), or indirectly like even the "most peaceful president" Carter supported the massacres in Indonesia.

overseen? Yes.

With Jackson, it's not overseen, it's orchestrated

Every president since the 70s has overseen genocide, even ignoring the one you're likely alluding too.
