The question is, what would it take to stop Israel from its destabilizing activities and help make it a constructive member of the international community?

What would it take was the question? And the only answer that comes to mind is an internal revolution and a complete twig and branch regime change supported by free and fair elections! Otherwise, Iran risks its sands being turned into vitrified glass where once were oil wells, homes and farms.

Highly unlikely. But, if it does happen, Israel has moral right on its side - and America. Iran is a rogue, terrorist nation that has been threatening Israel with annihilation since the mad mullahs took over.

This article is a bit dated. A near crisis has happened over the last week.

Since it was written Mossad has convinced the US that http://intelnews.org/2019/05/09/01-2544/ :

"Iran had made plans to target US forces in Iraq and elsewhere in the Middle East”. According to [US] ABC News, the intelligence suggested that “Iran or its proxies were planning attacks against US forces in Iraq, Syria and at sea”."

In response http://intelnews.org/2019/05/09/01-2544/ the:

"US announced that the USS Abraham Lincoln carrier strike group had received instructions to sail to the Middle East...while an unspecified number of B-52...bombers have been ordered to fly to a US military base in Qatar [near Iran]."

My criticisms include: The gesture of deploying the aircraft carrier and B-52s seems to neatly tie together two disturbing influences in the Trump Administration:

1. National Security Adviser John Bolton’s lifelong mission to trigger regime change in Iran by US/Israeli aerial bombing (including hitting Iran's already radioactive nuclear facilities) and

2. Trump son-in-law Jared Kushner’s (as Trump's designated supremo on Israeli affairs’) unexperience in international tension matters. Hence Kushner may over-react to Israeli government lines, with Kushner being manipulated by spy-romantic Mossad.

So how else is the author proposing to end the suffering of the Iranian people at the hands of the mullahs?

help make it a constructive member of the international community?

They first need to wake up to be constructive to themselves before the rest can take them serious as somewhat worthy of being accepted into the international community !
