The Western nations seem to be utterly blind to the life-and-death cultural differences between Islamic nations and the West. In his book, Planet Earth–2000 A.D: Will Mankind Survive, Hal Lindsey discusses a principle called “takiya”:
[Takiya is] the right within Islam to fake peace when you’re weak, so you can wait for better timing to conquer your enemy. There is a famous Arab saying: “When your enemy is strong, kiss his hand and pray that it will be broken one day.” Hudayblya is a small oasis between Mecca and Medina where Muhammad fought a battle in the early years of Islam. When he saw he was losing the struggle, Muhammad signed a 10-year peace agreement with the people of Mecca. Two years later, when his forces were stronger and the Meccans were living securely and off their guard, Muhammad marched into the city and captured it (pp.256-257. Reference is made to Isaac Cohen: Chicago Tribune, September 23, 1993).
Moreover there is yet another Muslim technique called: Tawriya (“Creative Lying”) advocated by Muslims. A doctrine that allows lying in just about any circumstance:
The authoritative Hans Wehr Arabic-English Dictionary defines tawriya as, “hiding, concealment; dissemblance, dissimulation, hypocrisy; equivocation, ambiguity, double-entendre, allusion.” Conjugates of the trilateral root of the word, w-r-y, appear in the Quran in the context of hiding or concealing something (e.g., 5:31, 7:26). As Sheikh al-Munajid puts it: “Tawriya is permissible if it is necessary or serves a Sharia interest.” Consider the countless “sharia interests” that can run directly counter to Western law and civilization; from empowering Islam, to subjugating infidels. To realize these Sharia interests, Muslims, through tawriya, are given a blank check to lie, which undoubtedly comes in handy–whether at high-level diplomatic meetings or the signing of peace-treaties.
