It is positive to see that the Yemeni jihadis have decided to give prewiring to the residents of Tel Aviv. A kind gesture. Their attacking Israel is a relatively new phenomena and it will take time to understand the value of life of an Israeli. The only way to be sure was to attack Tel Aviv and manage to kill one. So now it is clearer what the value of the dead Israeli means in terms of retribution. The Yemeni jihadis over the next few days can add up the toll from the first Israeli attack. Then the jihadis can calculate how many Israelis they can afford to kill over the next weeks and months.
