"Hamas, after its surprisingly successful and deadly attack on Israeli villages, is for now on top of the terrorism tree. It adheres to an extreme ideology that blends Islamism with Palestinian nationalism, dedicated to the destruction of Israel; its 'preferred methods include suicide bombings, rocket and mortar attacks, shootings, and kidnappings,' according to the the New York- and Berlin-based Counter Extremism Project.
...The broader impact of the Hamas attacks—even before a potentially escalating regional war—is the possibility that terrorist groups around the world will try to match the spectacular carnage that Hamas pulled off earlier this month, which had a death toll equivalent to multiple Sept. 11 attacks on a per capita basis in a small country such as Israel. The need for terror outfits to raise their own game is what will make them even more dangerous, said Hans-Jakob Schindler, the senior director of the Counter Extremism Project."
