There's some truth here as well, there's a very large political asymmetry at play here. On Iran's side, no death will really matter to the regime, it's a political hydra which is capable of doing and sustaining lots of damage to stay in power. On the US side though, the war is highly unpopular, every single death and every single side effect of the war is politically painful. But I don't agree about the first part, there's definitely a "we're the biggest military in the world, we will win no matter what" mindset in the US military, which is the reason why they lost so many wars. Having a military so large is a blessing and a curse, they are too confident and then trip on strategy.
