"Acts of terror against military occupation must be seen in historical context," Dugard says. "This is why every effort should be made to bring the occupation to a speedy end. Until this is done, peace cannot be expected, and violence will continue."

As long as there is occupation, there will be terrorism, Dugard argues.

Dugard was appointed in 2001 as an unpaid expert by the now-defunct U.N. Human Rights Commission to investigate only violations by the Israeli side, prompting Israel and the U.S. to dismiss his reports as one-sided. Israel refused to allow him to conduct a U.N.-mandated fact-finding mission on its Gaza offensive in 2006.
