Islam does indeed promise and preach peace, but the Mohammedan conception of peace is so severely defective the prima facia true assertion, "Islam is a religion of peace," becomes a lie. (Just as the Evil One's conception of life and death were so defective that the prima facia true "you will not die" -- neither Adam nor Eve died in the material sense we post-lapsarian humans and the already lapsed serpent use the word "die" -- was a lie, as mankind died to God in the Fall.)
The Semitic root slm is common to both islam = submission, and salem = shalom = peace. The only peace Muslims can conceive is the peace between conqueror and conquered, the peace between master and slave. Even "Islam means peace" is only a lie deep down, as to the Muslim peace and submission are identical. There are no negotiated peace treaties in Islamic law, only "hudna", ceasefires of at most ten-years duration, which Muslims are wont to break on any pretext if it is to their military and political advantage. There is no spiritual peace that a Christian or Buddhist or Hindu would recognize as such in Islam, only the peace between cowering slaves and the arbitrary tyrant that Muslims understand Allah to be.
“The real problem with the assertion “Islam is a religion of peace” is that....”
GWB never retracted that statement and many unthinking Americans still accept it as truth.
