Instead, research has focussed on how cyberattacks are unlikely to trigger a physically violent, interstate response, missing how these new weapons can worsen interstate relations in non-violent ways. To address this gap, I pose the question, do cyberattacks lead to a decline in interstate relations, while still avoiding physical conflict? States are incentivised to deter future attacks by responding to the incursion while avoiding costly, physical confrontation. However, the intensity of this response is likely to be influenced by their relationship with their attacker. Attacks launched by rivals can appear more threatening due to their history of conflict and therefore warrant more aggressive, non-violent responses. I therefore investigate whether cyberattacks lead to an increase in an attacked state’s defence budget and a reduction in diplomatic relations. While some support is found for states using these non-violent measures as a response to cyberattacks, the presence of a rivalry did not lead to the expected outcomes, due to weaknesses with the operationalisation of my variables. Nevertheless, my thesis indicates non-violent, negative measures are used in response to a cyberattack and therefore the impact of cyberweapons in damaging interstate relations should not be underestimated.Show less
