Iran a Threat to be or not to be

Last week president bush has declared Iran a threat, nothing has changed. Are they a threat ? and what are we to do about this, arnt we doing enough, or do we need to do more. We have been in iraq for the past 4 years has there been any acomplishments, let the public decide, Iraq just had their election and the turn out was a positive one, the number of people was record breaking. know back to being a threat to the US, well they are, how can we say they are not, we have not forgoten about 911 have we.
