This past week Europe experienced its second major terrorist attack within the last five months. The ISIS-claimed attack in Brussels signifies again just how real and how serious the militant group is about training, equipping, and tactically carrying out an assault in Europe. Although the attack appears to have been provoked or moved ahead of schedule due to the arrest of Salah Abdeslam (Belgium-born, French national personally involved in the Paris attacks), what is apparent is this attack was forthcoming based on the materials found in the apartment of the attackers, and the overall sophistication of the bombings suggests that this was not a reactionary, random plot. With details of the attackers released, their chief bomb maker Najim Laachraoui, along with two brothers Ibrahim and Khalid el-Barkraoui, are reported as Belgium nationals. As the search continues for the fourth perpetrator, questions are continually raised about where the next possible attack could be, or how to best combat an all-encompassing ISIS assault on Western Europe.
