Unfortunately the West has tried to change  the way that other people live. Spreading democracy was/is a common phrase. To some extent democracies tend to interfere with other countries while dictatorships attack their own people. 

So as a result of Britain interfering in the Middle East and environs for decades, the Muslims are seeking revenge and the Brits need soldiers on the streets. 

Democracies seems to be the problem.
