This step taken by Germany, and the two attempts to-date to arrest Livni, must not be taken according to their merits but rather the attitude they reflect. US and other powers certainly must have committed many crimes like these, but the world is getting intolerant of Israeli breaches. It sees Israel not only attack other people, but also colonising their land and driving them out. I don't know how you can buck this trend, but it may help if you would make peace with the Arabs.
