The world powers and Iran announced a significant framework of understanding about a process to limit Tehran's nuclear program.

While this is by no means the final deal, it is a step toward reaching a peaceful solution to Iran's nuclear weapons project.

And there is not worldwide agreement that this is a good deal. Both Israeli leaders and Iranian hardliners finally agree on one thing - that this is not a good agreement from their perspective. Congress remains skeptical of any agreement with Iran.

The agreement framework is as follows:

- Provide restrictions on Iran's centrifuge numbers, uranium stockpiles and enrichment capacity.

- In return, the European Union and the United States would terminate nuclear-related sanctions as Iran complies with the terms of any deal.

- And the International Atomic Energy Agency would be allowed to inspect anywhere it wants.

The Iranian commitments are for a minimum of 10 years and some of the international inspections can last as long as 25 years.

Congress and others are correct to be wary of Iran and its intentions. Yet that is no reason not to attempt to negotiate a workable agreement.

Who trusted the Soviet Union when Republican presidents Richard Nixon and Ronald Reagan both negotiated arms control agreements with the Soviet regime?

On both of those occasions, the Soviet Union had many nuclear weapons in place ready and targeted upon the United States and vice versa.

The final details of this agreement remain to be worked out. The June 30 deadline will give negotiators time to work toward a stronger agreement, as well as time for opponents to debate and investigate the agreement.

The reality is that sanctions against Iran have crippled Iran's economy along with low oil priceshave forced the Iranian regime to the negotiating table.

The time is right to continue negotiations in order to reach a satisfactory agreement for the United States and the world.
