This study is about the Bush-administration after the events of 9/11. Despite the fact that Israel-Palestine had no connection to 9/11 or Al-qaida, the Bush-administration changed their foreign policy regarding the Israel-Palestine issue. This thesis studies the motives behind the administration's change using a theoretical based motive analysis. The analysis intends to provide motive-based explanations with the help of international relations (IR) theory. To reduce the scope of the analysis, the thesis investigates if the security, identity and solidarity motives from the IR-theories realism and constructivism could be a possible cause for the change in policy. This study uses the Bush-administration’s own statements which were found at the White House archives, among others, to explore the motives correspondence. The analysis concludes that the motives: security,identity and solidarity, have been motives for the administration’s change in the Israel-Palestine issue and the motives have shown correspondence with reality. Both theories then show relevance for being able to study this issue and define motives from. This study also acknowledges the value of combining realism and constructivism to analyze this case.
