Tunnel War with the Hizballah

We are having a tridimensional war with the Hizballah religious party of Lebanon. In fact, we founded that Muslim organization, thinking that it will focus in humanitarian and social work in South Lebanon. You know, highly educated and intelligent people - in positions of power - tht were convinced that Lebanon's hostility was founded in poverty and destitution, so if we improve their life, they will love us. Hizballah IS basically a welfare organization but it has also organized an army focused on our destruction. They had fired missiles to our Northern cities, and we have built a tall prefab cement blocks wall. So they went underground and bored several tunnels to surprise us. They planned to send through the tunnels fighters on motorcycles, with mission of causing chaos. We have discovered three tunnels, we don't know how many are. The pic shows that these days they have erected a wall in the tunnel, to make difficult to Israeli soldiers to advance in it. Comparing this photo with the photos of Hamas tunnels, I think the Hamas's technique of prefab inverted U blocks is more effective. The Hizballah seems to have worse engineers, maybe because those in Gaza have worked and gathered experience in Israel.
