Final answer:
The fear of a second bomb attack is both a product of panic and a realistic concern, given past terrorist events like the Oklahoma City Bombing. Increased antiterrorism measures have been effective in preventing similar plots. Information on survival in disasters may help manage fear but their actual effectiveness is debated.
Step-by-step explanation:
The fears of a second bomb attack can be seen as a product of both panic and realistic concern. Instances like the Oklahoma City Bombing and the attack on the Boston Marathon have shown that the threat of terrorism is not just a theoretical concern. People's reactions to the event, such as increased media coverage and changes in security policy, can heighten the sense of urgency and sometimes lead to an overestimation of the risk involved. It's worth noting that after events of significant physical danger and loss of life, it is natural for people to worry about repeat occurrences. However, steps were taken to increase antiterrorism programs, which have been effective in preventing similar plots. Although it is unlikely that civilization could collapse due to such attacks, it is not unfounded for individuals to have worries about future dangers based on past incidents and ongoing threats.
During periods of uncertainty and fear, information on how to survive disasters, such as atomic bomb blasts, were disseminated. These instructions, including how to protect oneself from blast and heat, underline the public's fear and the government's effort to prepare civilians for potential emergencies. However, the effectiveness of such protective measures is debated, and it may be argued that the publication of booklets with these instructions was more about managing fear and showing governmental action than about offering realistically effective survival strategies.
