a little politics

should their plan encompass such tactics:

they're gonna blow up defense capabilities at south-west of Iran to make it easy for ISIS mercenaries to get inside from Iraq border.

they're gonna do the same at north-east for Taliban, and those many Afghans already "settled" in Khorasan are part of the plan to join their military.

those who have infiltrated the borders to operate the recent uprisings and did a lot of damage, again come forth and commit even worse acts and maybe they are accompanied by a number of people from disgruntled and even gray population and capture some areas such as small towns or even military sites and acquire huge amount of military assets. 

alongside, the deployed US armed forces continue bombing every place they count as military sites relentlessly.

and surely they assassinate officers and even president and other titles in power and a quite number of hardliners but I'm not sure about the supreme leader.

aside from who will succeed in the war and weather the goals will be achieved, two problems should be addressed before pulling the trigger:

1. how to end this war 

2. what will become of Iran in the aftermath 

as soon as they come up with plausible plans meeting these problems they will start the war without hesitation. 

BUT, will they find solutions? that's the key point everything hinges on.

me?

they can pound Iran like Tyson hitting a cat which I do not see enough to achieve their high goals. 

and I like to believe they know that too. 

in case of the first problem, my opinion is that they are not on the driver seat so that whenever or wherever they deem enough they can pull over and end the war therefore ending the war is either in the hands of Iranians or "the limited strike" will turn into a war of attrition and no one knows who's gonna raise their hand and give up.

in case of the second problem which is the hardest part for Americans to solve and is the most important part, I think there are some possibilities. 1. Iran turns into the next Syria which except of Israelis none of neighbors are interested in even the US is not interested in because such a ruined country is detrimental to all. middle east will lose security for years and who knows what might happen to oil industry in the region. 2. the US will succeed precisely in regime change with the least casualties and commit the power to the hand of pro-American parties (I do not know of). 3. Iran rises from its ashes like phoenix. and that's the scariest possibility for Iran's enemies. 

if Americans have the same thoughts on the second problem as I do, they will never ever start war with Iran, BUT do they?
