erm.... actually it's some people in the US and Israel who are begging to attack Iran. The politicians in the US are beholden to the Israel lobby to such an extent that most prioritise Israel's interests over US ones in the middle east. The US has no real strategic concern with Iran beyond a basic stability that keeps the strait of Hormuz open to oil tanker shipping.
Those who REALLY want to attack Iran are the Israeli far right, partly concerned about the 'destroy Israel' rhetoric coming from Iran (which is really mostly rhetoric), but mostly because they want to stay the only nuclear-capable country in the region (which allows them pretty much a free hand in dealing with Palestine without the other Arab countries interfering).
Sure there are some ultra-religious Islamist nuts in Iran ranting on about the great satan, executing gay people and blowing up Buddha statues, but they're no different from the ultra-orthodox Jews in Israel who are intent on permanently occupying the whole of the west bank. nor from the right-wing Christianists* in the US.
*Christianist = Christian version of Islamists. Christians are in favour of love, peace and charity, Christianists are in favour of capital punishment, torture, war on non-Christians, and entrenching their religious prejudices in the US constitution. Since they can't execute gays in the US, they materially support this practice in places such as Uganda.
