The late Nizzar Rayyan on Israel. Goldblog:
The question I wrestle with constantly is whether Hamas is truly, theologically implacable. That is to say, whether the organization can remain true to its understanding of Islamic law and God's word and yet enter into a long-term non-aggression treaty with Israel. I tend to think not, though I've noticed over the years a certain plasticity of belief among some Hamas ideologues. Also, this is the Middle East, so anything is possible.
I suspect that's the correct level of expectation.
