Well, it is simple, really. Greenwald definitely possesses a boatload of good sense and is intellectually scrupulous, as this passage makes clear:
I'm going to leave the debate about whether Iran's election was "stolen" and the domestic implications within Iran to people who actually know what they're talking about (which is a very small subset of the class purporting to possess such knowledge). But there is one point I want to make about the vocal and dramatic expressions of solidarity with Iranians issuing from some quarters in the U.S.
Much of the same faction now claiming such concern for the welfare of The Iranian People are the same people who have long been advocating a military attack on Iran and the dropping of large numbers of bombs on their country — actions which would result in the slaughter of many of those very same Iranian People. During the presidential campaign, John McCain infamously sang about Bomb, Bomb, Bombing Iran. The Wall St. Journal
published a war screed from Commentary's Norman Podhoretz entitled "The Case for Bombing Iran," and following that, Podhoretz said in an interview that he "hopes and prays" that the U.S. "bombs the Iranians." John Bolton and Joe Lieberman advocated the same bombing campaign, while Bill Kristol — with typical prescience — hopefully suggested that Bush might bomb Iran if Obama were elected. Rudy Giuliani actually said he would be open to a first-strike nuclear attack on Iran in order to stop their nuclear program.
Imagine how many of the people protesting this week would be dead if any of these bombing advocates had their way — just as those who paraded around (and still parade around) under the banner of Liberating the Iraqi People caused the deaths of hundreds of thousands of them, at least. Hopefully, one of the principal benefits of the turmoil in Iran is that it humanizes whoever the latest Enemy is. Advocating a so-called "attack on Iran" or "bombing Iran" in fact means slaughtering huge numbers of the very same people who are on the streets of Tehran inspiring so many — obliterating their homes and workplaces, destroying their communities, shattering the infrastructure of their society and their lives. The same is true every time we start mulling the prospect of attacking and bombing another country as though it's some abstract decision in a video game.
And, to be sure, Greenwald pummels the right sort of folks by holding them accountable for what they say, write and do. He is indispensible.
