Add up the cost of every terrorist attack on American and European soil, including 9/11 and 7/11. Then add the much larger cost of anti-terrorist security measures. The cost of expanding the Air Marshall program, the cost of all the extra security at airports and government buildings. And then there's the more intangible cost, of people who don't fly planes, don't feel safe, of children who grow up with their first memory of the towers falling down. Of parents who will never come home and wars fought around the world in pursuit of those who sent their parent's murderers to these shores.
The tidal flood of Islam driven to Western shores has brought with it a greater threat of terrorism, but it has also caused a heavy strain on social services. Whether it's Pakistanis in the UK, Somalis in the US or Indonesians in Australia-- Muslim immigrants remain heavy consumers of social services. Breeding large families on limited incomes is difficult, and liberal politicians have long ago learned that the surest way of binding new immigrants to their political machine, is to foster their dependency through social services. Today some of the worst enemies of England live heavily on the dole.
Furthermore one mechanism behind the large Muslim birthrate is polygamy. While in their home countries polygamy tends to be reserved for those who can afford it, Western social services create a boom in state sponsored polygamy. Muslims who are Western citizens will import young brides from their home countries as their sisters or nieces, legalize them, privately marry them and then when they're pregnant, on official records they're single mothers living with their "brother" or "uncle", while being supported by the state.
Under the shadow of these arrangements, Muslim men can harbor several wives, creating constantly expanding families where abuse and honor killings easily proliferate. And the taxpayers foot the bill.
When the quiet violence goes public when a body is found, the newspapers wonder how this happened. The real answer of course is that it was happening all along. Polygamy is slavery. Muslim men trafficking in women is a form of sex slavery, regulated by Muslim religious authorities and enforced with ruthless brutality. The difference is that it's the only form of sex slavery funded by Western taxpayers.
And then there's the crime. Beyond the actual terrorism, funded by Jizya, or 10 percent of every believing Muslim's income, there is the culture of crime that Muslim immigration brings with it. From gangs such as the Muslim Boys in the UK, to the glorification of violence against non-Muslims common among French Muslim rappers, to the common street level violence pervading everywhere from Oslo to Sydney to Paris, crime is part of the high cost of Islam.
Islam does not merely teach Muslims to reject the laws of the land they live in as the law of the Kafir from the Dar Al Harb, the portion of the world yet not conquered by Islam, but teaches them to view themselves as conquerors bringing the rule of Islam wherever they go. Little wonder that Muslims routinely practice rape, robbery and smuggling -- all practices that date back to Mohammed's campaign against the "infidels".
Beyond the human cost of Muslim crime, in the form of murder, assault and rape victims-- there is the large scale social disruption. Drug smuggling, car theft rings and riots are all examples of large scale Muslim organized acts of crime that tear apart the very fabric of society. In France, even rape has managed to reach that scale with the Tournade becoming a large scale social problem as well.
Every time Muslims riot, more money is poured on the problem in the form of social service centers, many of them run and funded by Muslims in order to stop radicalism. This money naturally goes to fund the very problems they're meant to stop. Since the problems are themselves inherent in Islam.
All this adds to the high cost of Islam. As the social problems of the Muslim world are exported to the West by way of immigration or terrorism, promoted by our dependence on fossil fuels and the dhimmi political correctness of cowed majorities in the West, the cost continues to skyrocket. And ultimately the final cost of Islam will be the destruction of the West, if the dread tide is not turned back first.
