I like to think that Israel has let other terror states know that it will not go quietly, that in addition to Iran it will take out Syria, Egypt, Jordan and maybe others that have supported terrorism.
Substitute SA for Jordan.
You think correctly.
Depending on the legnth of time before Israel is attacked, (rogue state nukes?) will determine how Israel responds.
Should the world sit around, biting their nails and asking for us all to just get along, and otherwise not be willing to confront the realities of the situation, Israel will do just what you have suggested. They will have no other choice.
If you have college aged children, suggest that they take graduate courses in enviromental purification. There will be a worldwide need for cleanup technicians.
