If Protesters Don't want US Support, Why Are Their Signs in English?

clipped from www.weeklystandard.com I know that the protesters in Iran don't want the United States to interfere with their efforts in any way. I know this because John Kerry says it's true, and because every Democrat in government and the media is telling us that the people of Iran want the United States to keep quiet and not become, in President Obama's words, a "political football" in the standoff between the regime and the protesters. (Never mind reports of crowds gathered outside police stations pleading, “Obama, please help us, they are killing our young children.”) But there is one fact that doesn't jibe with the left's absolute certainty that this administration's silence is precisely what the protesters being beaten in the streets of Tehran want most from America -- the pictures. All the pictures show protesters holding signs in...English. To what end? Why would they want to galvanize support for their movement in the outside world if the only thing they want from the outside world is silence?
