Now I'm not an international scholar here but I think I understand certain aspects of human nature. I understand that what is persuasive to one person, or type of person, may not work with another. (flashing blue and red causes most people to pull over but we need spike strips for those who just aren't convinced)
Here's how I think that this ought to be applied to the Islamonutjobs we are encountering in Iraq/Iran/Crapistan/etc.
Bottom line: I care more about American's sons and daughters than I do about Iraq/Iran/Crapistan/etc's sons and daughters. I care more about Americans interests (security, economic, moral, etc) than I do about these other backwards countries.
So put me in charge of this war and my first official order says that all terrorists (loosely defined as "anyone that even has a bad dream about looking sideways at one of our soldiers") who are captured get thrown in a 5 X 5 cell naked with feral swine as cellmates.
Any and all interogation techniques that are deemed effective by the men on the ground will be employed. (as opposed to letting the men in the suits who lie for a living and pretend to care about "the folks" while making 3.8 times the median salary of the American worker and working about 1/8 as hard decide what "feels good")
Our soldiers would be authorized to shoot/blow up/incinerate anything that even looks suspicious.
Terrorists who are killed in battle are buried with pig guts, pig heads, pig feces, etc. Crude headstones with phrases such as "Where's your Allah now?" and "If those pigs were a virgins does that count?" would be erected over these graves.
Terrorists who were identified (captured or killed) would have their families houses destroyed.
As for nation states who contribute to our boys dying in any way shape or form (Iran and co): I can't put a value on the life of an American citizen and I will not try to. So I'm just going to use a round number: one of our soldiers/citizens lives is worth 50,000 lives of your citizens.
We'll start by nuking Tehran and two or three major cities in Iran and if they still want to play after that then the 50,000 rule comes into play. WE WILL BURY YOU.
Egregious examples of rooting against America from the media would result in arrest for treason. You do not have a first amendment right to encourage bloodthirsty savages to continue fighting.
What I'm saying is that I would become more vicious than the enemy. I would attack them with their own facist religion and deny them their heaven. I would get the intestinal fortitude to use our weapons that are more powerful than their weapons. I would terrorize them until they begged us to stop.
