Wow it would be really wonderful a peaceful world, without weapons, where everybody will consider others as his brother, hear his reason instead of the anger, and.... Yes, i absolutely agree with you, it would be wonderful, but it's not the reality!
The reality is the fact that we can't really understand the action of Israel, and the absence of action of the international community, because they are a lot of political, financial, stategical interests we don't know, because information from Israel and Liban has been reinterpreted by media when arriving in our countries.
The real reason of this new war, we'll never know it before 10 years, as usual.
