The economy is vital to the existence of the Iranian regime and the major motive behind the nuclear deal. However, so far Tehran has not achieved what it wants or attained what it was promised.

Its biggest disappointment has been the obstruction by a US Congressional subcommittee of a $24-billion deal to sell 100 Boeing planes, which would have been the biggest deal in Iran’s history, and the most prominent item on its American shopping list.

The subcommittee’s decision includes European Airbus factories, which will be banned from selling to Iran 118 passenger jets because they contain US-manufactured parts. US legislators have not left politicians and tradesmen any way around the ban. Many parties testified before the subcommittee that Iran uses commercial airlines to transfer gunmen, arms and funds to Syria, Lebanon and Yemen.

The committee warned Boeing that it would be an accomplice in such practices if the deal was implemented, and the company acknowledged that it would have no say in how Iran uses the planes. It seems the US government has no desire to defend the deal, which is another indication of the coldness of relations with Tehran despite the nuclear agreement.

Even if the White House decided to challenge Congress, it would require a lot of time — time the current administration does not have since President Barack Obama’s term ends in less than five months.

Tehran has either not yet woken up from the shock of the decision, or is trying to remain calm. Newly-appointed Foreign Ministry spokesperson Bahram Qassemi said: “We don’t care what’s happening in terms of (US) internal affairs. We expect the American government to honor its pledges.”

The weakest point in the body of the Iranian regime is not military or political, it is economic. It is the Achilles’ heel.

International boycotts had suffocated the Iranian regime and would have threatened its existence had it not given in and signed the deal freezing its nuclear program. If it does not achieve the desired trade through this deal, it will face a difficult political crisis domestically.

Iran disappointed Western politicians who thought the nuclear deal would make it a positive power in the region. The regime has in fact become more evil, increasing its hostile military activity in the region. Its relationship with the West is still shrouded with mutual doubt, and the deal’s results are still controversial. There are doubts regarding Tehran’s behavior following reports that it seeks equipment relating to nuclear production on the European market.

In addition, the relevant parties have not yet finished forming the team tasked with monitoring the nuclear deal.
