There comes a point where we must begin to question the reasons behind a situation which seems unsolvable, such as the tension between the U.S. and Iran. We should not lose our patriotism, but at the same time, we should take the time to look at both sides and do our research in order to come to our own conclusions.
We know what we are told, and often hidden facts are swept under the rug so that we can be persuaded to point our finger at those who refuse to follow the ‘American way.' Many are unaware that Iran in fact had a democracy and simply wanted to tend to themselves, until the U.S. intervened.
This video provides a brief history, an important piece of information that we should give a few minutes to in order to have that freedom to draw OUR OWN opinion.

To build nuclear weapon one should posses certain facilities to assembly the weapon. It is a very large project, and it is quite costly because nobody wants to make nuclear weapon in gun-type style because it is too heavy. And therefore, useless.
Iran is not building WMD, not it posses a facility to make one.
They just need electricity, oil rafineries and other infrastructure, not weapons of war.
