One underlying explanation for this is that highly lethal pathogenscan kill their hosts before theyhave a chance to spread, so there is a selective pressure for pathogens not to be highly lethal.Therefore, pathogens are likely to co-evolve with their hosts rather than kill all possible hosts.39 Recent developments in biotechnology may, however, give people the capability to design pathogens which overcome thistrade-off. Some gain-of-function research has demonstrated the feasibility of altering pathogens to create strains with dangerous new features, such as vaccine-resistant smallpox40 and human-transmissible avian flu,41 with the potential to kill millions or even billions of people.For an engineered pathogen to derail humanity’s long-term future, it would probably have to have extremely high fatality rates or destroy reproductive capability(so that it killed or prevented reproduction by all or nearly all of its victims), be extremely infectious(so that it had global reach), and have delayed onsetof symptoms(so that we would fail to notice the problem and mount a response in time).42 Making such
a pathogen would be close to impossible at present. However, the cost of the technology is falling rapidly, and adequate expertise and modern laboratories are becoming more available. Consequently, states and perhaps even terrorist groups couldeventually gain the capacityto create pathogens which could deliberately or accidentally cause an existential catastrophe.Escalation in Syria risks WMD warStirling 2011– Governor & Lord Lieutenant of Canada, Lord High Admiral of Nova Scotia, & B.Sc. in Pol.

Any massive WMD usage against Israel will resultinthe usage of Israeli thermonuclear warheads against Araband Persian populationscenters in large parts of the Middle East, with the resulting spread of radioactive fallout over large parts of the Northern Hemisphere. However, the first use of nukes is apt to be lower yield warheads directed against Iranian underground facilities including both nuclear sites and governmental command and control and leadership bunkers, with some limited strikes also likely early-on in Syrian territory.¶ The Iranians arewell prepared to launch a global Advanced Biological Warfare terrorismbased strike againstnot only Israel and American and allied forces in the Middle Eastbut alsoagainst the American, Canadian, British, French, German, Italian, etc., homelands.Thiswill utilize
