Egypt pushing troops into Sinai DMZ

IMRA has the following story. It seems the Egyptians are getting security-conscious all of a sudden. In the Taba area, that is, and not just South of Gaza, where Jew-murdering scum has been smuggling their weapons and explosives from Egyptian army bases.

Again: What is Egypt preparing for? Or just threatening, keeping Israel too tied up to do other things like take out Tehran?

Update: Just a thought but... Since there are many conspiracy theories on the motive and perpetrators for the Taba massacre circulating already, I'll just add my own.

The Egyptians did it. They get to murder sone Jews, get away with it, AND they now have an excuse (if not an actual reason) to deploy more troops in this area. Cool eh?
