Knowing is not the same as believing. ICE shoot innocent people in the street but there's still enough Fox News watching idiots who believe the victims somehow had it coming. Now take that and add no Internet access, no independent media, living under sanctions, etc.

If the Fox news watching Americans can be broadly supportive of this war, you'd best believe that there's an equally large contingent of Iranians who feel an equal and opposite antipathy towards the US.
