Iran Missile Tests: Statements from the Candidates

John McCain:

“Iran's most recent missile tests demonstrate again the dangers it poses to its neighbors and to the wider region, especially Israel. Ballistic missile testing coupled with Iran's continued refusal to cease its nuclear activities should unite the international community in efforts to counter Iran's dangerous ambitions. Iran's missile tests also demonstrate the need for effective missile defense now and in the future, and this includes missile defense in Europe as is planned with the Czech Republic and Poland. Working with our European and regional allies is the best way to meet the threat posed by Iran, not unilateral concessions that undermine multilateral diplomacy.”

At an avail earlier, he also mentioned that he had voted for the Senate resolution designating Iran's Islamic Revolutionary Guard Corps as a terrorist organization but that Obama had missed the vote and opposed the resolution because it was "too provocative." (Here's a clip of that statement.) He's correct on both counts, but it's wrong to imply (as McCain has in the past) that Obama thinks the IRGC is not a terrorist organization.
Obama's statement:

“These missile tests demonstrate once again that we need to change our policy to deal aggressively with the threat posed by the Iranian regime. Through its nuclear program, missile capability, meddling in Iraq, support for terrorism, and threats against Israel, Iran now poses the greatest strategic challenge to the United States in the region in a generation. Now is the time to work with our friends and allies, and to pursue direct and aggressive diplomacy with the Iranian regime backed by tougher unilateral and multilateral sanctions. It's time to offer the Iranians a clear choice between increased costs for continuing their troubling behavior, and concrete incentives that would come if they change course.

“As these tests have reaffirmed, the threat from Iran's nuclear program is real and it is grave. As President, I will do everything in my power to eliminate that threat, and that must begin with direct, aggressive, and sustained diplomacy.”

I think this is one area where Obama has not drifted that far to the right.
