They know they can get away with anything, and it's making all of us less safe. I don't get how policy makers in the West don't see that this is going to cause waves of lone wolf attacks in the next decades, especially if they allow Israel to go through with their plan to push Gazans into Egypt.
And that's just taking the purely selfish view, not the obviously morally correct view of not allowing genocides to happen and pushing for justice for all peoples, something nobody in charge in the West outside of Ireland seems to be interested in.
