Israel does not attack unless provoked. When did Israel invade Lebanon?
In 2000, under the useless U.N., Israel pulled out of Southern Lebanon, and of course Hezbollah moved right in. From there, Hezbollah randomly attacked patrols near the boarder. Israel never returned fire.
Finely, in 2006, Hezbollah fired mortars into Israeli cities from southern Lebanon, and Israel launched an all out war.
Now since you think you got the answers, what would you have done?
You claim both sides are just reacting to each other. I disagree. Israel is reacting. Hamas is provoking. Do you realize how many years the violence in palestine was minimal? Do you know how many times Israel has not reacted to the Arabs in an effort of peace? You remember that Israel offered to give Arafat nearly half of their land for peace, and he refused?
This is because peace has never been a goal for the Arabs in palestine. The only goal is the complete destruction and slaughter of Israel and all the Jews there. Even the Gaza Strip itself, was offered on a platter to Eqypt after Israel won the war. Eqypt refused, and even built a wall around the Gaza boarder. They don't want peace. They want the death of Israel, and nothing less.
