@sprite1275 That is why they are levelling the buildings. Getting some manoeuvre room for the tanks, blocking some tunnels. Then they just need to locate an entrance or two and start to burn diesel fuel and then watch for where the smoke exits and trace it from there whilst flushing out gunmen.I'm not sure they will go in to Gaza. I reckon it would be hell in there trying to fight.
But also if they do I'm surprised they haven't already. You would think they would have a complete plan drawn up of what they would do in this situation. The longer they wait the more hamas will be digging in setting traps etc.
