Final answer:
A chronological approach to informative speech design is best suited for discussing the evolution of international terrorism over the past 20 years, shedding light on the transition from state conflicts to transnational challenges with terror groups like al-Qaeda and ISIS. The approach highlights key events and the complexity of tackling terrorism, which transcends traditional diplomacy and the borders of nation-states.
Step-by-step explanation:
An informative speech design that would work best for tracing the evolution of international terrorism over the past 20 years is a chronological approach. This allows for a clear and organized presentation of events over time, showcasing how terrorist activities and methods have changed. It provides a timeline that can illustrate the shift from traditional state conflicts to complex challenges with nonstate entities, such as al-Qaeda and ISIS, which utilize modern technology to spread their message via social media and conduct attacks across the globe. The informative speech would incorporate the increasing complexity of international relations due to terrorism being a transnational issue, requiring intelligence gathering and targeted military intervention rather than traditional diplomacy.
Key events to highlight might include the 9/11 attacks, the rise of ISIS, the role of intelligence in targeting terrorist organizations, and the adaptation of terrorist tactics involving cyber elements. The speech could discuss the effectiveness of various foreign policy approaches, including the hybrid approach of combining different schools of thought as exhibited by President Obama's administration. By emphasizing the transnational nature of terrorism, the audience can understand the difficulty in tackling this issue through a singular state-centered lens.
