Stand Against Terrorism, Even in Iran

There is only one acceptable response to Wednesday's deadly terrorist attacks in Iran: swift and unequivocal condemnation of the perpetrators, and condolences to the victims. By joining the other world leaders who have offered their sympathy, U.S. President Donald Trump can reaffirm both America's standing in the community of nations and its determination to defeat terrorism, whatever and wherever its source.

Yes, there is an obvious irony here: The U.S. has rightly condemned Iran's long history of support for violence and funding of groups such as Lebanese Hezbollah and Palestinian Hamas. Washington's sanctions on the Tehran government for this, as well as human-rights abuses and violations of United Nations' strictures on missile defense, will remain in place. But this is not the moment to talk of just deserts.
