According to several security reports, the popularity of Hamza Bin Laden, the son of Osama Bin Laden, is increasing and some reports suggest that amongst followers of Al Qaeda, he is actually more popular than Al Zawahiri.

The gradual fall of ISIS in Syria and Iraq is likely to result in the growth of other groups in the terrorist scene.  We are already starting to see the appearance of a new generation of Al Qaeda. ISIS increased the brutality and global reach of the Jihadi movement, so any group that steps into its shoes is likely to step up on both those factors suggesting we should expect devastating attacks in large cities in Europe and the US as new groups step into the void left by ISIS – likely to use similar tactics as ISIS, such as lone wolf attacks.

Al Baghdadi in pushing terrorist actions in North Africa and with the attack of Paris is applying the tactics of contingency.

There is not an optimal strategy for Isis, jihadi leaders know clearly that it's always the scenario to make a winning strategy. When the theaters of conflict are changed to the saturation of the possible new areas, the psychological defensive ability of the opponents weaken, making useless the prevention. 

With the list of countries targeted by terrorism growing, we are starting to see an impact on the internal policies of various other countries also impacted. Concern is particularly growing in Europe as a result of the level of involvement many of its citizens and residents have in these terrorist groups.
