As said they need to be carefull, the world will turn on them and then thing could well get very nasty.
They absolutely need to be careful and the world is rightly watching.
Right now, I doubt they give a hoot about how the world perceives them though and that can be seen through speeches at the UN etc.
The sooner Netanyahu answers for his mistakes the better and the sooner Israel can hopefully turn towards a more moderate government the better but that feels a while off yet unfortunately.
