Agreements with these people are not worth the paper they'e written on. The concept is "taqqya" - deception in the advancement of Islam. Basically a "get out of jail free" card for any kind of lying, decipt, stealing, murder, kidnapping, rape, or anything else as long as it can be justified as "advancing Islam."
(NB - I don't think that the more liberal Muslim thinkers are guilty of this, but they appear to be distinctly in the minority in current Islamic thought, at least outside this country).
