These types of resolutions are referred to as "a sense of Congress," or an opinion that urges actions or issues.
Maud Easter, a spokeswoman for Women Against War, said the strong language used in the current resolution is eerily familiar to that used before the Iraq invasion and that she doesn't want to see another war.
"This is very poignant for McNulty. He voted for the authorization that gave Bush the green light to go to war with Iraq and subsequently said he made a mistake and apologized and I respect him very much for that," Easter said. "We don't want him to, and don't really think he would want to, make the same mistake again."
After McNulty announced that he wanted to change the resolution's wording, Easter said, "We were very happy and so pleased he had the courage to do this."
The resolution doesn't use the word blockade, but states that economic sanctions could be imposed through the use of search and detainment.
"Whereas the November 2007 National Intelligence Estimate reported that Iran was secretly working on the design and manufacture of a nuclear warhead until at least 2003," the resolution states, "but that Iran could have enough highly enriched uranium for a nuclear weapon as soon as late 2009."
In order to curtail Iran's nuclear activity the resolution "demands that the President initiate an international effort to immediately and dramatically increase the economic, political and diplomatic pressure on Iran to verifiably suspend its nuclear enrichment activities by prohibiting the export to Iran of all refined petroleum products; imposing stringent inspection requirements on all persons, vehicles, ships, planes, trains, and cargo entering or departing Iran; and prohibiting the international movement of all Iranian officials not involved in negotiating."
McNulty said he understood the group's concerns but that there is a clause in the resolution that states, "Whereas nothing in this resolution shall be construed as an authorization of the use of force against Iran."
