Bedouin Insurgency?

Issandr links to Seneferu's argument that the idea of a Bedouin insurgency is "stupid". What might be the best argument:

"If you are still unconvinced, it is the bedouins themselves of these regions who are denying this, and rightly offended in their honour by this claim. Their living depends on tourism...why would they destroy their only source of livelihood? Is it because they were offended so bad by the Egyptian government that they had to go and attack international peacekeepers?"

I think the word "insurgency" is probably misplaced here, but am open to the idea that there is a dispute being carried on by violent means with its origins in Cairo's Sinai policy.
