In reply to SFrancis:
I'd be asking what it is that you're concerned about.
If it's personal safety then I don't think there's a lot to be worried about. Wadi Rum is (relatively) a long way from the very concentrated fighting in Gaza, and even if the conflict were to escalate more widely across the Middle East - which seems quite unlikely given that it hasn't happened yet - then Jordan isn't likely to play an active role.
If it's to help out the people of Wadi Rum, who are probably suffering ecomically through no fault of their own, then I'd say going there could make a positive difference (albeit a small one).
