Sura 2, verses roughly 180 through 190, explains it. Muslims are commanded by Allah to "Kill the infidel wherever you find him". In other words, anyone who is not in their cult is to be killed. Christians and Jews, being "People of the Book" are to be offered the opportunity to convert but if they refuse they are to be killed.
As a bonus, dying a martyr in the process of killing infidels is a Muslim's only sure and certain ticket into heaven.
Elsewhere in the book you will find detailed instructions on how to abuse "Infidels" if for some reason killing them is inconvenient.
This is my understanding of Islam based on my reading of the Koran over the past 23 years.
Have you read the Talmud? Have the people who control the media even let you know that such a thing existed?
Check out Gittin 58a3-4 and get back to me on your thoughts of Christians having a religious duty to support Israel.
My understanding about the islamic belief system is the same as yours.
