Israel needs to dispense with all the secrecy regarding its nuke arsenals , and clearly state : such and such of your cities are on our target lists and if you make any moves to attack us in support of Hamas , or Hezbollah , you will die by the millions without further warning or notice . Further state that Mecca and Medina and Tehran are also on the targeting list . Just lay it out there , and mean it .
Not a nuke weapons expert, but can Israel bomb in Gaza or southern Lebanon without effecting it’s own country, radiation etc.
