Two members of the U.S. House of Representatives from the Republican Party have joined a chorus of colleagues raising major concerns over a provisional agreement between Boeing and Iran involving a multi-billion dollar purchase of a hundred commercial airliners. Lawmakers on the Hill are sounding alarm bells over possible significant national security repercussions in this regard.

U.S. companies must not play a role in “weaponizing” the regime ruling in Iran is the core of a strong joint statement made recently by House Financial Services Committee Chairman Jeb Hensarling (R-TX) and Rep. Peter Roskam (R-IL), a member of the Ways and Means Committee.

“We strongly oppose the potential sale of military-fungible products to terrorism’s central supplier,” the two lawmakers wrote in a damning June 16th letter to Boeing CEO Dennis Muilenburg, citing the major implications of such a deal. The U.S. State Department has in fresh reports -- most recently on June 2nd -- once again designated Iran as “the foremost state sponsor of terrorism” and emphasized Tehran’s support of terrorism has not diminished at all.

If this deal receives a green light, it would represent a major contract and breakthrough between a U.S. firm and Iran following nuclear “implementation day” back in January when sanctions began to ease on the regime in return for the mullahs curbing a controversial and clandestine nuclear program engulfed in major suspicions of involving a drive to obtain nuclear weapons.

“In light of recent reports that a deal is imminent, we seek information to assist the U.S. Congress in determining the national security implications of a potential sale of Boeing aircraft to Iran," Hensarling and Roskam continued in their strongly-worded letter.

Iran is also claiming to be on track to a parallel purchase from Airbus, Boeing’s European rival, according to various news reports. The Washington Times, however, raised doubts over Iran boasting success in this regard.

“The Airbus deal to sell more than 100 planes to the Iranians made headlines in January but ‘still hasn’t been finalized. And one of the reasons is that Airbus has had a terribly difficult time finding a private financial institution to bank the deal,’” The Times wrote, citing Eric Lorber, a former attorney in the U.S. Treasury Department’s office of foreign assets control.

“The risks associated with doing business with Iran haven’t changed,” The Times went on to quote Chip Poncy, former head of the Treasury’s office of strategic policy for terrorist financing and financial crimes through 2013.

Despite all this, U.S. president Barack Obama, continuing his so-far failed appeasement policy vis-à-vis Iran, is strongly backing the possibility of a lucrative Boeing-Iran deal. This has only fueled growing concerns over Iran’s nature of remaining a significant “source of funds and banking services” for leading terrorist groups wreaking havoc across the globe.

While Obama may be lobbying for the deal, a potential kink will definitely stem from outstanding U.S. sanctions that continue to cast a heavy shadow on Iran and ban the use and access to the U.S. dollar for any party possibly interested in doing trade with Tehran. If such sanctions remain intact, as seems to be the case up to this point, any thinkable Boeing-Iran deal will be forced to seek non-U.S. financing. This is one hurdle Iran simply cannot surpass, and Boeing will suffer huge losses in such a challenging endeavor.

Boeing has been asked to respond by July 1st to ten serious questions raised by U.S. lawmakers. Members of Congress are currently dissatisfied, saying the Chicago-based plane manufacturer is refusing to relieve the concerns raised by lawmakers over their ongoing discussions with Iran. This will naturally not play well in Washington and place even more obstacles before the Obama administration in its promotion of the deal.

Hensarling and Roskam continued in further concerns over the arrangement, saying Iran’s “commercial aviation sector has been deeply involved in supporting hostile actors.”

Senator John Cornyn (R-TX) has sought to target the Revolutionary Guards-affiliated Mahan Airline in Iran, describing the company as a “terrorist airline or airways.”

"[Iran’s] largest commercial airline is the number-one state sponsor of terrorism," The Hill cited Senator Cornyn saying. "This airline has repeatedly played a role in exporting Iran's terrorism."

Saudi Arabia took a similar approach in banning Mahan from using its airspace, Bloomberg reported on May 25th.

Iran’s military, especially the Revolutionary Guards and its terrorist-designated extraterritorial wing, the Quds Force, are known to frequently dispatch troops, send weapons and even rocket and missiles across the globe by way of commercial airliners. This notorious effort has procured the arms needed for groups such as the Lebanese Hizb’allah and the dictatorship of Bashar al-Assad in Syria that has leveled his own country for over five years now, leading to over 400,000 deaths, according to some estimates, scores more injured and the largest refugee crisis since World War II. This onslaught has rendered millions displaced inside the country and seeking refuge abroad, with no end in sight. With the international community failing to respond, Iran has successfully developed and cemented deep-seated terror across the region, leaving barely any room for optimism.

Iran is looking to modernize its aging fleet by replacing a gigantic number of 400 planes. As far-fetched as the extent of this effort remains considering Iran’s disastrous economic conditions three years into the tenure of the so-called moderate President Hassan Rouhani, such an initiative will most definitely further fuel Iran’s support for international terrorism and boost the mullahs’ effort to continue inflicting mayhem in conflicts plaguing the Middle East, from Iraq to Syria, Yemen, and beyond.

At a time when the Obama administration is continuously failing to rise to the occasion against such deeply hazardous enterprises, the efforts of Congress might by the last chance to spearhead the incorporation of a vital, universal concept to halt Tehran’s dangerous campaign aimed at solidifying its means of spreading absolute terrorism, ushering in growing extremism and Islamic fundamentalism.
