This hilarious video will show you why war-hungry Republicans hate the Iran deal

Before the ink had a chance to dry on the Iran nuclear deal, Republicans were vowing to kill it.

The historic agreement, which restricts Tehran’s nuclear program in exchange for lifting of economic and financial sanctions, has been described by opponents as a "historic mistake," "dangerous" and "one of America's worst diplomatic failures." 

Many progressives and peace activists in the United States fear that Republican opposition, along with skepticism among some Democrats, could scuttle the deal and perhaps lead eventually to war with Iran.

Obama has promised to veto any legislative attempt to block it, and it will be very hard for the House and Senate to muster the two-thirds majorities necessary to override that veto. But 2016 is just around the corner …

With that in mind some pro-Iran nuclear deal groups have initiated a petition aimed at stopping Republicans from sabotaging the accord and marching toward a fresh war in the Middle East.

To help get their message across, they have joined forces with Funny or Die to create a parody of the 2010 action film "The Expendables" called "The Dealbreakers (The Expendables: A Congressional Parody)," featuring a group of gun-toting, warmongering Republican senators who literally blast the Iran deal to smithereens. 

In the spoof trailer, one of the senators asks rhetorically: "You think we can't get away with this shit again?"

Despite the opposition to the pact, which is the result of years of tough talks involving Tehran and six world powers led by the United States, it could go down as President Barack Obama’s greatest foreign policy achievement. (Assuming it doesn't all go horribly wrong.)

"Today after two years of negotiation the United States together with the international community has achieved something that decades of animosity has not: a comprehensive long-term deal with Iran that will prevent it from obtaining a nuclear weapon," Obama said Tuesday.

"This deal is not built on trust. It's built on verification.”

Obama talks at length about the deal in this interview with New York Times columnist Thomas Friedman. 

But trying to get Republicans — and a few Democrats — to agree to it will be difficult, if not impossible. 

Even before they had seen the details of the accord, which will be sent to Congress for a 60-day review before being put to a vote, Republicans were denouncing the deal as a catastrophic mistake that will guarantee a nuclear-armed Tehran and a Middle East arms race.

That's not to say there aren't legitimate concerns about the deal. There are. 

Iran is a big country — it’s more than twice the size of Texas — which will make it difficult for nuclear inspectors seeking to verify that Tehran is complying with the terms of the deal. If Iran decides to cheat — which is a real risk — will the West find out in time to prevent the worst possible outcome?

But much of the reaction so far has verged on the hysterical, particularly among Republican presidential hopefuls who are keen to flex their foreign policy muscles in front of their supporters.

Jeb Bush compared the pact to “appeasement” — a not-so-subtle reference to British Prime Minister Neville Chamberlain’s failed attempt to avoid World War II by granting some of Hitler’s territorial demands.

Lindsey Graham told Fox News: “… what the president has done, [is] he's taken the world's most destabilizing power, one of our chief antagonists — [Iran] killed hundreds of Americans in Iraq — and he's guaranteed that they're going to become a nuclear nation.”

Mike Huckabee had this to say on Twitter:

Because that's what the United States and the rest of the world needs right now — another war.
