Selected claim, supporting its parent
The arms races created a
'security dilemma'
where opposing states obtained more arms to defend against their aggressor, ultimately increasing tensions.
Pros
Cons
Pro claim 1
When engaged in a security dilemma, it is difficult to tell if one's opponent's intentions are defensive or offensive. Therefore, it is always rational to prepare for the worst-case scenario.
Pro claim 2
As historian Christopher Clark argues, the inability of European leaders to read each other's intentions meant they did little to quash tensions and
refused to deviate
from their war plans.
Con claim 1
The security dilemma approach assumes that the escalation to war was an accidental process. However, there is good evidence that
Germany had been planning for war
far before 1914.
