Islamism is a political trend. It will be excised by its own inefficacy!! People whose solutions to all the worlds problems is Islam, cannot but fail to govern in a way that is even remotely approaching competency. Arab socialism and Arab Nationalism were the dominant political trends of the 20th century. It was the failures of those political ideologies, mixed with the promotion of Islamism by America and American backed dicators, the withdrawal of state services that accompanied the rise of neoliberalism (and Muslim organizations stepping in in their place), and the rise in influence of Gulf oil states (where the most radical strands of Islam originate) that saw Islamism rise as a force. It will fall away as soon as people realize Islamism isn't equipped to deal with the problems of a modern state. The thing to worry about is not that it will spread across the globe, nor the specter of Islam that is spreading over Europe, nor any other such bigoted nonsense. It is that hundreds of thousands of people in the Middle East (if not more) will lose their lives and homes before the rest of the people of the region realize this.
