It is no secret that the IDF has been preparing for war in September. They have been having the soldiers prepare for riots in Judea and Samaria and in Jerusalem, and for bombs both in the south and in the north.
In addition Israel is preparing for war on a different front, by using the media. For internal consumption there is this article, about how Netanyahu and the opposition leader Livni have met for the first time in months. Even if the meeting was trivial the government made a move to give the appearance of some type of unity.
For external consumption there was the article about how we are being prepared in our yishuvim in Judea and Samaria to handle violence that is expected in September. The truth is that our rapid response team on the yishuv is always being trained in one way or another. The fact that the IDF is releasing a statement about it is perhaps a way to deter some of the expected riots.
Of course the statements by the IDF Chief of Staff Benny Gantz are meant to give warning that Israel will not stand for more terror in the south and is another way to prepare the world for the next war in Gaza.
