Did Netanyahoo remind the world that the US is the only nation to have used nuclear weapons, for racist purposes?
Hardly racist. We just wanted Japan to surrender and end the reign of terror they were inflicting upon the world.
It was the right thing to do, and it really has no bearing on Iran's illegal nuclear program.
Did N remind the world that it was the US that overthrew Iran's democratic government simply to steal Iran's oil wealth?
You got two things wrong there.
overthrew Iran's democratic government. The US acquiesced, but we were hardly "the reason" the coup happened.
Second, it was the UK who was up in arms about the oil. And rightly so, because contrary to your claim, it was the UK's oil, and it was Iran who was doing the stealing.
