The deal that the United States has negotiated with Iran poses a grave threat to American security at home and abroad.

U.S. officials know that Iran has had a long-term plan to gain a nuclear weapon and destabilize the region through its support of terrorist organizations. And it is known that President Rouhani has never agreed to full and unfettered United Nations inspections of Iran’s nuclear facilities.

The Iranian government has repeatedly, flagrantly violated sanctions put in place by the United Nations. We know that they have flat-out lied about every nuclear facility they have built over the last three decades.

This is not the behavior of a potential ally or of a partner. These are the actions of a country trying to bluff its way into persuading the United Nations, the United States, and its allies to allow it the freedom to develop a nuclear weapon for military purposes.

This is not an agreement which will make Americans proud.

Because of these facts, we cannot trust anything they sign. Until Iran is prepared to (and opens its nuclear facilities to) full and unfettered UN-sanctioned inspections and demonstrates that they are willing to halt uranium enrichment, we cannot place any trust in any deal that is made. 

This is not an agreement which will make Americans proud.

The message we have sent by making this deal is simple: Take our diplomats hostage for 444 days. Kill our soldiers. Cheat, lie, and be a menace to our allies in the Middle East. Raise the cost of international security, threaten your neighbors in the Persian Gulf, and support terrorist groups. Assassinate dissidents abroad and kill young Iranians who are fed up with your tyranny. Do all of that and we will reward you. We will treat you like a partner, like an ally, and we will place our trust in you.

This message has been received by Iran and by our allies, all of whom will view this deal as a capitulation by Washington. We were once viewed as an international leader that our allies could rely upon. We demonstrated our strength and capabilities, protected human rights, and led the fight to stamp out terrorism. We are sending a message to the world now that rogue governments can quash free speech, sponsor terrorism and denigrate our way of life, all with the tacit consent of the United States government.

The Iranian government has requested untenable concessions to legitimize their earlier violations of international law -- and this administration has given in to these requests. The U.N. Security Council has repeatedly called for Iran to stop its uranium enrichment efforts, but this deal recognizes Iran’s right to enrich uranium. Iran secretly built numerous uranium enrichment facilities in violation of its Nuclear Nonproliferation Treaty commitments. This deal would legitimize those facilities.

This is not an agreement which will make Americans proud. It is not a deal that demonstrates our strength and resolve at home and abroad. Our allies will not point to this as a signal of our continued support.

It is a sad chapter of American history when President Obama and Secretaries Kerry and Clinton are more concerned with their legacy than they are with our national security. Unfortunately, this behavior is no longer unexpected; it continues six years of alienating our allies, weakening our international stature, and negotiating with states who have demonstrated that they cannot be trusted.

Too often, this administration has presented the American people with a choice: follow our flawed national security strategy that destabilizes regions and undermines our allies or commits thousands of American ground troops to a protracted war. This is a false choice. There are other options -- and a bi-partisan Congress should insist on voicing their opposition to this deal. We have many other options that have been left unexplored or underutilized. We should start by providing the support our Jordanian, Egyptian, Kurdish, Saudi, and Emirati allies have asked for. 

We cannot let this agreement with Iran follow the disastrous Russian “reset” orchestrated by former Secretary of State Hillary Clinton. We cannot make concessions to a government which will then take advantage of our trust. We must meet these governments with strength.

This type of foreign policy cannot continue. We must stand up for our allies and for our American interests. We must re-assert American leadership and strength abroad. The world is a more dangerous and tragic place when America is not leading. For these reasons, we cannot and must not accept this deal with Iran.
