According to Sharia law, waging a Holy War of Extermination (Jihad) against Infidel nations is every Muslim's command, with Infidels to be given 3 CHOICES: (a) Embrace Islam; (b) Submit to Islamic rule as oppressed Dhimmi minority ("One State Solution"); (c) Endless war under threat of destruction. Arab leaders well know that if they break above Sharia rules their verdict is certain death - see Abdullah I of Jordan, Anwar Sadat or what Arafat was afraid of at Camp David II. There are only 3 REMEDIES to counter this: (a) Decisively defeat and expel Arab Jihadists beyond insurmountable boundaries (happened only in Iberia, Sicily, Malta); (b) Sign temporary truce (Hudna), which Arab Jihadists are allowed for up to 10 years until stronger and able to stage more lethal assault (back to Sq. 1!); (c) Evacuate and emigrate to another land. Take your pick! Everything else is just wishful thinking...
