Dynamic Map of the Crusades vs the Global Jihad

Some of you may have seen this.  It is such a powerful resource that I wanted to post it here.  Share widely.

Raymond Ibrahim offers this introduction:

Speaking of the Crusades (as Obama recently did ), Dr. Bill Warner of the Center for the Study of Political Islam has created a nifty video (below) that maps out the location and amount of jihads throughout the centuries versus the location and amount of crusades throughout the centuries.   The sheer volume and ubiquity of jihads radically dwarfs the much more maligned crusades � placing in context the significance, or need, for the latter, which as discussed here, were �in every way defensive wars.�

For a text list of the battles Bill Warner refers to, see his post The Jihad That Led to the Crusades.
