Iran still very much a threat - U.S!

It seems that after all that was said and done, the United states still believes Iran to be very much threat and that they still believe in going ahead with the missile defense shield plans. The baggage of past relations is one that Henry Kissinger would probably understand the best of all of us, for none more than he would know how history can have this resounding effect on relations for decades to come.
Look at South Korea and North Korea, technically they are still supposed to be at war, and that was over 50 years ago, so record wise that may be the longest war that has ever been fought in the modern history of man, not counting the 100 years war. One can only hope that both Iran and the United states find some peaceful way of resolving their issues!
