The Commission, led by former Sens. Bob Graham (D-Fla.) and Jim Talent (R-Mo.), said in a report released this week that terrorists are determined to orchestrate a large-scale attack unless drastic measures are taken to prevent such an occurance.

"The commission believes that unless the world community acts decisively and with great urgency, it is likely that a weapon of mass destruction will be used in a terrorist attack somewhere in the world by the end of 2013," Graham said upon the release of the report.
