Al Quaeda didn't make the Russians and Americans team up to wipe out Islam. So why would an alien attack?
Well Al-Qaida only attacked the US, it did unite Americans until the media decided division sells. The theory is that if we had a common enemy we would be united. But as you say if a bomb went off in Moscow especially at that time, they aint gunna wait to see if Manhattan went rogue, they're gunna nuke us.
Maybe I'm wrong, but I thought-in the book-the only site that was destroyed was a portion of New York. That's why I drew the Al Quaeda comparison.
Like 9/11, in Watchmen (the book) the US was attacked by an outside force that posed a threat to the entire world. Unlike 9/11, in Watchmen that resulted in the US and USSR putting aside their differences.
