The key question about Islamist participation in politics, let's call it the inclusion hypothesis, is whether when confronted with the mundane demands of politics the Islamists will put aside some of their ideological verities in order to get things done and in order to survive politically. There is ample evidence that non-Islamists routinely do just that, one might think of the National Religious party of Israel, for instance. Moreover, the Ak party of Turkey, arguably Islamist at its core, has manifested the same pragmatism. So,will Hamas be any different?

'Israel and the United States,' he said, 'want a Palestinian Authority that serves their interests.'"
