Right now, it's okay to ignore. Ahmadinejad is making of a fool of himself and actually doing us a favor. Would the Swedish condemnation of Iran have been so strong if Ahmadinejad would've been more subtle? If he continues, Iran will be politically isolated. It may not be long also before the private sector starts boycotting Iran as they do us. If that happens economic hardship will cause his downfall. We just need to keep close observation. Israel should continue to strategize it's defense against a military threat by Iran. But for now, action is really not necessary.
