As for how difficult it would be for Islamic fascist terrorists to force our fellow Americans to convert to Islam, just ask the Muslims over at Fox News.
We need for our military forces to take down Iran's military forces and denazify the people of Iran. That action would break the morale of Islamic fascism worldwide. Iran is their big hope for conquering the world. Such military action by our government would destroy their will to fight.
I don't know about that. Phares and others have pointed out the divisions in Islam. What you say is perhaps true of Shia Islam, but a defeat of Iran wouldn't necessarily stop the Salafists and Al-Q'aeda (who aren't the same thing) from continuing to obtain WMD with which to batter the West to its knees with super-terrorist, megadeath atrocities. Osama Bin Laden has been explicit about seeking to inflict such damage on the West, and as long as the Pakis have a nuclear arsenal, and as long as Bin Laden has nuclear technology available at some level, he still has a card to play.
I agree. Many people have argued that they did not "convert" to anything, since it was done under threat and has no interior effect, so to speak. But to the Muslims, the propaganda value is the same. And whether these guys acknowledge it or not, from the Islamic point of view - where forced conversions are not only allowed but have been the main way of spreading the cult since its inception - they have put themselves under sharia. Muslims believe now that we really don't care what we say or do and will submit gladly after a few gruesome examples (whether beheadings or 9/11) followed by steady threats. It worked for Mohammed and our pimply-faced jihadi is pretty sure it will work for him.
