Can the United States one day be a Muslim country ?

Yes it can as long as :

1)    The Americans are ignorant about what Islam really is.

2)    The Islamic organizations continue to have hidden and manifest activities. There are a lot of them.

3)    The Muslim fundamentalists keep on making use of the freedom of religion offered by the American constitution in order to fulfill their plans.

4)    The percentage of giving birth among Muslims increases while American births decrease.

5)    Mosques keep on spreading the call for vicious hostility for the American community and address them as disbelievers in their speeches.

6)    Muslims keep on spreading the idea of Jihad (strife) between American Muslims which lead to the incidents increasingly carried in the US from time to time.  The officer, who killed his fellows in the military base in Texas, is a good example.

7)    Increasing illegal emigration from the Islamic Countries.
