Since 2006, the Conservative government has consistently supported the state of Israel. This support creates a lot of controversy because it is interpreted as a break with the traditional Canadian position on the Israel-Palestine conflict. In this paper, we examine the position of Conservatives Joe Clark and Brian Mulroney, in order to evaluate how the Conservatives’ current position, under Harper, is different from those of the past. Finally, the paper reviews the explanations that have been suggested to understand the current Conservative support and we conclude that if there is break, there is also some continuity between Harper and other Conservatives.
