The current war with Hamas is focusing on a new and frightening element, one which did not feature prominently in any previous war. Until now, our wars have included soldier-to-soldier combat, tanks, planes, bridges, ships, airports and weapons, but during Operation Protective Edge, much of the focus has been on a new threat: the tunnels.

For the first time, the threat is not above ground; it's hidden below. Over the years, Hamas has created a virtual labyrinth of tunnels beneath the ground. The deadly network originates from basements and private homes in Gaza and extends into Israel—a tool for mass terrorist attacks against Jews.

In order to counter this threat, the IDF has had to dig deep, under hospitals, mosques and private homes, where they've discovered caches of weapons, guns, machine guns, RPG rocket launchers, tranquilizers, IDF uniforms and more—all with the potential to inflict untold harm on the Jewish nation.

Operation Protective Edge has exposed these tunnels, but it has also created a new kind of tunnel: tunnels of love.

During this war, we've dug deep into ourselves and discovered powerful tunnels of love crisscrossing our nation, connecting us to one another and to our brothers and sisters in Israel. We are, regardless of outward differences, a nation that cares deeply.

My brother, Dr. Motti Vigler, chief of hand surgery at Rabin Medical Center, dropped everything this week in order to attend the funeral of someone he had never met. Lone soldier Sean Carmeli was killed in battle, and his family all live in America. When my brother arrived, he discovered 20,000 people had come to the funeral to honor this brave hero. A day later, another lone soldier, Max Steinberg, was killed, and 30,000 people showed up for his funeral as well.

And the tunnels of love continue to expand and extend. At the shiva, 300 people, almost all of them complete strangers, showed up to comfort the parents of these brave young men. Strangers on the streets show an incredible amount of care and concern for one another, even during these most stressful times. A stranger uses his body to shield a father and son from a rocket attack. Breslever chassidim dance with soldiers on the front lines. Chabad brings care packages. People from all walks of life, from all over the world, are connecting through tunnels of love and compassion to provide the IDF soldiers with whatever they need.

Hamas may have built tunnels of terror, but we are building and maintaining tunnels of love. We may be different on the outside—one seems to be secular, another ultra-Orthodox, one a kibbutznik, another chassidic—but when it really matters, we know how to ignore the external differences and dig deep, focusing on our commonalities: we are one nation, with one heart and one soul.

We are currently in the annual three-week period of mourning for the destruction of the Holy Temple. The Temple was destroyed because of acts of wanton hatred, and it will be rebuilt through acts of love and kindness.

So, nu, G‑d, what are you waiting for?!
