The special representative for Iran, Brian Hook, remarked that "just a few days ago, we unveiled new evidence of Iran's missile proliferation. Three days later, they test-launched another medium-range ballistic missile. We have been warning the world for some time that we are accumulating risk of a regional conflict if we do not deter Iran's missile testing and proliferation". Asserting that Iran's missiles program is "not defensive in nature", Hook added that "we are making progress towards getting a proposal tabled in Brussels that would designate the individuals and the entities that are facilitating Iran's missile program. It is a grave and escalating threat".
