Final answer:
Modern global terrorism differs from historical terrorism in the complexity and variety of the goals of the terrorists, and the scale of the attacks, leading to a higher number of casualties and indiscriminate damage.
Step-by-step explanation:
In the section introduction, Dr. McCarty discusses how modern global terrorism differs from earlier forms of terrorism.
He mentions that modern terrorism is characterized by two main changes. Primarily, there is the transformation in the goals of the terrorists, which have become more complex and varied over time.
Secondly, there has been a shift in scale, with modern terrorist attacks often resulting in a higher number of casualties and indiscriminate damage, possibly due to the increase in global connectivity and access to advanced technologies by terrorist groups.
