Look at every war throughout history. Have there been civilian casualties? Of course. It's not pleasant, but that's what war is. As for the "occupation," Israel unilaterally gave up Gaza and returned it to Palestinian control. What did their leaders do with that? They built hundreds of miles of tunnels from which to fire rockets into Israel and launch terrorist attacks. They could have used that money to build schools, develop beachfront tourist attractions, fed and nourished their population. They chose terrorism and the demand that Israel be wiped of the map. Sorry, no government would sit back and allow this to occur to their citizens. Not the US, not Syria, not Russia. Hamas bit off more than it can chew and it will now pay the price. And, the price has to be high enough that their population never allows terrorists to run their government again.
