Abstract
This paper analyses a newly collected time-series database measuring the dimensions of violent political conflict in Egypt. Attention is focused on the interaction between politically motivated attacks by Islamists and the counter-insurgency measures used by the Egyptian government. The intensity of security force activities responds immediately to all kinds of Islamist violence, regardless of the target of the attack. However, there are significant asymmetries in the way that the different forms of Islamist violence respond to the different security force activities.
