If legitimate elections had been held in the 1930s -- 1940s, the Muslim Brotherhood would have been swept to power, as they were in 2012, in Egypt's first real elections. This explains why the Saudis so quickly joined the Egyptian coupmakers--the real 'kafirs'--in 2013 to crush the Brotherhood. They saw that they would be forced to allow elections after the Brotherhood success, and that would mean their demise.
The current battle is indeed a 'clash of civilizations ' as coined by US analyst Francis Fukuyama, though we should keep in mind Gandhi's proviso. When asked what he thought of western civilization, he answered, "I think it would be a very good idea." Already by the 1930s, it was clear to any thinking, moral person that the new order of capitalism, being spread around the world by imperialism, was amoral, without genuine culture.
Though all religions seek to have morality at the heart of society, now only Islam stands firm to resist the disintegration of society. This is because Islam puts political and economic obligations at its heart.
Despite the travails in the Middle East, and the misguided policies of the US and its Saudi accomplice, we can be hopeful: Islam is alive and well, and holds at its heart a firm believe in the spiritual nature of man and society, and the obligation of Muslims to work actively to promote this.
