Iran has killed hundreds of thousands innocent civilians over the last decade. No one else is responsible for them shooting down a civilian airliner over their airspace.
Nothing Trump did forced Iran to shoot down a civilian airliner in its own airspace. Not by any sane or rational standard.
Using their logic, Obama is to blame for those civilian deaths since the Iran Deal clearly helped Iran purchase surface-to-air missiles.
Or we can agree that solely Iran is responsible....
