If Obama did say that Iran is a tiny country that doesn't pose a serious threat to the US then it is hard to imagine how anybody could vote for him to be President of the United States. Such inane reasoning would be laughable in a State Senator. It is dismaying and repulsive in a US senator and would be dangerous beyond belief in a president.
This would be like saying in the 1930s that Japan and Germany weren't threats to the US because they were tiny countries.
It is true that the relative might of the US versus Iran is greater than the relative strengths of 1940 Japan and the US. Nonetheless we are not concerned about Iran launching traditional attacks on US soil. Iran is not going to send over its Air Force and bomb US cities. However there can be a co-ordinated series of attacks (snipers, bombs, suicide attacks and the like) by infiltrated Iranian soldiers.
