Mostly I agree with the view of prophecynut. the walls must be interpretted in a broader sense. Even if there may be some check points, if EU or UN takes care of the security of the whole land, Israel will not be able to excercise the sovereignty fully. EU and UN may say that they will guarantee the peace completely and it may be very difficult to reject such proposal as international community press. We do not know what kind of scenario will come true, but we will just observe with the keen attention. Gog might mean Grusia, in Greek it could mean Georgia or George. Gruzia is one of important part of USSR and its president was Sevardnaje (I don't know the exact spelling of his name) Ariel Sharon was very much hardline before 2003. Someone say he was totally changed since he was brain washed by Catholic after he met some Catholic in 2003 (in Vatican?)
The whole development asks us to be vigilant and be prepared for His second coming.
