The election of Rouhani is a gift to the Argentine government of Cristina Fernández de Kirchner, who was already moving in the opposite direction to her prosecutor – rapidly forgetting her nation’s history by normalizing relations with the Islamic Republic’s soon-to-be former president Mahmoud Ahmadinejad and pushing the bombing investigation into cold storage.

Journalist: Prosecutor Tied Rouhani to Argentina Terror Attack 

The late Argentinian prosecutor Alberto Nisman accused Iran’s President Hassan Rouhani of involvement in planning the July 1994 terror attack on the AMIA Jewish Center in Buenos Aires, journalist Andres Oppenheimer of The Miami Herald reportedWednesday.

Andrés Oppenheimer:

Nisman told me that Rouhani was not among the eight Iranian officials whose international arrest he had requested to Interpol in 2006, but that he was a member of the committee that had planned the attack. Nisman added that a key witness, a former Iranian VIVEK official named Abolghasem Mesbahi, had testified that Rouhani was a member of the Vijeh committee at the time of the bombing.

Today:
January, 2015, Who Killed Alberto Nisman?
First his death was declared a suicide; now Argentina’s president says it was the work of her enemies. What about Tehran?

If Nisman was murdered, it involved a level of sophistication not normally associated with Argentina but not uncommon for Iran. Tehran has more than 40 years of experience knocking off meddlesome individuals abroad and is now trying to allay global distrust as it bamboozles Barack Obama about its nuclear-weapons program. Nisman’s search for truth may have put a target on his back.

More evidence points to a murder:

Argentinian federal prosecutor Alberto Nisman was shot from a distance of at least 15 centimeters [6 inches]
. . .
The finding completely contradicts the government’s initial claims that Nisman had committed suicide, an assertion president Cristina Fernandez Kirchner has since backtracked from.

The forensics exam also confirmed that there was no exit wound, a result expected when a gun is pressed to the temple, the Federal Police source said.

Elsewhere, journalist Damián Patcher, who first broke the news of Nisman’s death,

Encontraron al fiscal Alberto Nisman en el baño de su casa de Puerto Madero sobre un charco de sangre. No respiraba. Los médicos están allí.

had to flee Argentina in fear for his life:

After I left Argentina I found out that the government was still publishing wrong information about me on social media. The Twitter feed of Casa Rosada, the Argentine presidential palace, posted the details of the airline ticket I had bought, and claimed that I intended to return to Argentina by February 2 — in other words, I hadn’t really fled the country. In fact, my return date is in December.

The government proudly tweeted the details, thereby showing they’re keeping an eye on people,
