One of them countries will not have nukes now and hopefully with the next presidency neither of them will have an arm's race or war.

If you pay attention to history Iran and Iraq were at war constantly.

Saudi's needed a cushion, Saudi's are America's "friend" therefore it made perfect sense at the time to take out Iraq. Iraq has the largest oil reserves in the world it would make little sense to put it in the hands of Iranians or have it sit there as Iraq continued defending itself from Iranian invasion and Iranian funded terrorism.

Pretty simple if you ask me.

PS: Some of you people are the dumbest mother fuckers in the world and really have no business in things you have no idea about. I do not claim to know it all here but the above is one of my guesses.
