In a 2004 interview, Obama endorsed internationalism, and lamented our not being a member of the ICC:
CC: But would you agree that by doing what the Bush administration is doing we are fomenting... BO: We are exacerbating it! Our adventures in Iraq are appealing to some of the worst impulses in the Arab and Muslim world rather than the best impulses of those cultures. I think it’s emblematic of a general arrogance of this administration that was on display before Iraq — it was true with our unilateral rejection of the Kyoto Protocol, we could have done something about greenhouse gases, it was true of our unilateral rejection of the international criminal court which, had we been a signatory, could have actually dealt with Saddam Hussein in an appropriate setting. It was true with our unilateral rejection of the landmines treaty. This administration has repeatedly shown disregard for other countries and world opinion. That is fundamentally a mistake...I think that has made us less secure.
