So it is okay for the United States to invade Iraq and destroy an entire country, but Iran is the aggressor because they then join the fighting -- when the country is their neighbor.

There is no right and wrong and black and grey in this, that's what you don't understand...

Of course Iran could be our ally -- a tenuous ally, but yes, an ally.

Their parliament chants Death to America? How many times has OUR congress threaten to invade their country?

Put the petty shit behind you... You have to understand, most of the world views the US as the biggest threat to world peace. So whatever ideas you have about the US being "right" then I need to understand your reasoning.
