The IDF's actions should not be a surprise
Abused children, when unchecked end up abusers themselves. The IDF, born out of the need to provide the safety for an ethnic group that faced near extinction in WWII, is now capable of doing just that.
Let's get one thing straight, the IDF is a very effective killing machine. Its objective is to safeguard the citizens of Israel. It will operate under what it thinks is necessary to achieve those objectives. The value and sanctity of human life beyond the borders of Israel is meaningless, and is irrelevant to the objectives of that organization. Furthermore, the superior ability to apply destruction and carnage and the ability to think rationally does not mean that the underlying barbarism of such a machine is diminished. We, the Lebanese, knew that very well back in 1982. There's nothing new.
Having a democratic society, a western-friendly image, and massive superiority in the ability to apply organized violence does not make this act by the state of Israel any less barbaric. Violence is violence is violence, not matter how fancy and sanitized and "smart" and "precise" its instruments are. The Israelis have delegated their security to a soul-less machine, and we can't blame the beast (the IDF) for being a beast. It is the Israeli people's choice and they have their own journey and moral path. Yistiflo minnon la rabbon.
Let's not victimize ourselves. I think that the question is not how we feel about this or who to blame, but rather what can we do to maintain our existance as sane, dignified and productive people. We need to keep a level head when we deal with this, and not lose track of the fact that the IDF's actions are providing us with more and more moral clarity about our country's plight and unity. We will win the peace by being rational AND by not losing touch with our humanity.
... and by refusing to curl up and die. We will keep procreating until they kill everyone of us. We will keep going to school and working abroad, and keep sending money home. We will rebuild our bridges WITH OUR OWN HANDS - NOT THOSE OF MIGRANT WORKERS - a hundred times over if we have to. This is our country, and we only have ourselves to fend for it, not the Americans nor the French nor the Saudis nor the Iranians and nor the Syrians.
The questions should always be, "what do we want next?" and "what is the smartest way to achieve that?"
