Israel warns its citizens, sinai attack

So we have it all over the papers;
Israel warns her citizens to stay away from Sinai, because of attack threats.
Well,
every single one of the previous attacks had threats preceeding them,
but why did it reach isreal first this time?
And why didn't the egyptian government explain or tell anyone that they caught a truck load of explosives somewhere near areish?
Why are all young arab men being discriminated against? even in their own home!
Any egyptian, just walking on his "supposed" land, in his "supposed" country, can be just swept of the street and disapear, randomly, (but thats a bad case) or( a current norm), be interogated, body searched and treated like scum
I lost track of one of my best friends who is in dahab, for 3 hours, why? Because he was being interogated ........................for having a laptop, NO not just interogated, they took the thing apart!
Great work! Some "inteligence" indeed!
