Attacks with a cocktail of Biological Agents has a high killing rate with relatively low infrastructural damage. More importantly, it is the psychological effects of the diseases that is most insidious. Some countries have a spike in suicides and child abuses as both parents and their children are infected with encephalitis. In other countries the same disease leads to a spike in college shootings and police brutality. In the former case, children and teenage students were the targets of the attack, and in the latter, the police was also targeted.
It is unfortunate if a country reacts to such attacks only after the pandemic unfolds, it is disastrous if the country is irresponsible.
Be forewarned.
