Some say 0%, some say 100%....I think both would be wrong, but that's just my opinion. Sam Harris says about 300 million (20% of all Muslims) are either Jihadists or Islamists - he cites polls over the years, and America being the biggest entity to stand in the way of their dream of spreading Islamic Sharia Law, it would make sense that they want America destroyed, since America stands in the way of implementing "god's law". So 300 million is a logical starting point. Question: how many Muslims do you think want America destroyed? Zero? Half a billion? How many?
