Winston Churchill once wrote "It’s not the government that makes war in a democracy, but the people – and the people are asleep in the free democracies today, lulled into inaction by a ‘softening up’ process of our enemy."
Is Islam the 'enemy' of the West? Italy has thousands of polygamous, frequently unhappy marriages, the state appears to turn a blind eye in the name of 'cultural sensitivity'. In Britain and Spain, where large Muslim communities also have settled, some officials favour recognizing polygamous marriage as a way to ensure the wives' access to pensions, medical care and other state benefits.
