This historical study assesses the determining factors behind the development of the Netherlands as one of Israel’s most faithful European allies in its conflict with the Palestinians. As such it wants to contribute to the academic debate on foreign policy Europeanisation that started two decades ago with the publication of Ben Tonra’s seminal study on The Europeanisation of National Foreign Policy. Comprehensive studies using primary sources of the EU’s individual member states’ policies towards the Israeli-Palestinian conflict continue to be scarce.
