i'm somewhere not far from hitchens on iran, if you want a reference. i disagreed with him about iraq, but this is a contextual thing - there was no serious opposition on the ground, and the bombing was punitive rather than productive.
i also opposed the action in libya (for similar reasons) and continue to oppose military action in syria (against assad, i mean. i supported the bombing of isis.).
but, i might have supported an invasion of iran in 2003, and i might support one tomorrow, or in 2023.
i don't think that governments should pretend they can determine what's "moral" and what isn't, but i would challenge the claim that military action against iran would be immoral.
the iranian regime is one of the most brutally vicious regimes on the planet, and has been for the entire extent of my lifetime. the oppression suffered by the iranian people since the 1979 counter-revolution has been worse than those suffered by almost any other people on earth.
i am an insurrectionary anarchist; i am in favour of struggle, of revolution. there is no place on earth where such a revolution is more justified than iran. there is no government anywhere that deserves to be torn down more than the one in iran.
and, no leftist would write off the oppression perpetuated by the iranian government by appeals to cultural relativism. the iranian people have spoken out about their hardships. to assign the iranian people a lesser concept of freedom, or a lesser concept of democracy, based on the tyrannical dictates and brutality of their existing ruling class would be blatantly racist. their women deserve the same rights as women everywhere else. their queers deserve the same rights as queers everywhere else. and, if you will not stand with them against the government and the religion that oppresses them, you have no reasonable claim to stand on the left - you are a reactionary liberal and must stand with the bourgeois rulers you sympathize with.
so, my solidarity is where it has always been - with the secular left in iran, the socialists, the atheists and those seeking to overthrow the totalitarian state.
i have nothing but disdain for those that would stand with the mullahs. you are on the wrong side of history. you will be struck down.
