How does terrorism affect land control in intrastate conflicts? This article explores this question in the case of the Israeli-Palestinian conflict during the Second Intifada (2000-2005), and shows that Palestinian attacks led to an expansion of Israeli outposts in the disputed territories of the West Bank. Following suicide attacks, there is an increase in outposts in home districts of the perpetrators. The number of outposts also increases following deadly attacks against Israelis in West Bank districts where these attacks take place. These results suggest that Israeli settlers use outpost expansion as retaliation against Palestinian communities they perceive to be involved in violence, and this shifts territorial control against Palestinians.
