Bush gave countries the feeling that "I don't like what America is doing but we can eventually get back to normal". Trump gave countries the feeling that "We can never trust America again".
I think it's the opposite. Bush admin were establishment Republicans that spilled over from Bush Sr/Reagan/Ford-Nixon years Trump wasn't a party guy so may be seen as more of an aberration.
Yup, its a given... Bush shouldn't have gone into Iraq. But whatever the death toll was, it will probably be exceeded by the number of deaths Trump could have prevented had he handled covid better.
Iraq War led to 500k+ deaths. Trump is responsible for some of US's covid deaths but not all or even most.
But then, Bush never locked hundreds of children in cages after separating them from their families.
I'm sure he did it with Muslims.
But anyways, i've already argued Trump is a worse POTUS than Dubya. Both are moron a-holes.
