After the Bush National Security apparatus announced that Iran had stopped it's program, the Israelis new it was a lie. Plan B went into overdrive.
After Obama was elected the Israelis began planning for an attack on Iranian installations which has only gotten more complex and risky with the passage of time. They listened patiently to Obama never trusting him but they went with the American rouse and self-dseception.
In the last 3 years the Plan is GO.
Obama has been lying and losing ground at at ever increasing pace and the Israelis know it.
Plan B is an Israeli attack on key Iranian installations.
Israel needs to nuke the key installations of the Iranians. Then there is no doubt of their destruction. So JugEars secondarily causes a nuclear war. Sounds about right to me.
