Let me google that for youWhen did Israel threaten its neighbors?
The only country Israel ever "threatened" with war is Iran.
For Once, Iran is not a neighbor of Israel.
Second, It's not really a threat. Israel won't attack Iran anytime soon, it's pure "watch out of me, don't test my muscle, i'm the bigger bully in the street" kind of thing. the Monkey Ahmedinejad threatens to wipe Israel off, Netanyahu send Liberman to be the payback, it's all like a game between kids.
Facts that leaders yell at each other is not a threat. Beni Gantz is the boss here. plain Govt' words are just words.
and Third, even if Israels threatening Iran will one day proved being more then thratening, that is what you do when someone threatens to qipe you out of the world's map. They will not be able to whine afterwards.
