America knows exactly what it's doing. They love any chance to invade a country with a reason the public can get behind and going after dem terrorists that r threatening r freedoms is a perfect excuse and always an easy sell.
no America (by that i mean the government) doesn't know what its doing.
if it knew what it was doing it would understand that you can't spend a trillion dollars on a war when your enemy spends less than a million.
especially when you are already deeply in debt from the last war and barely hanging on by continued borrowing and money printing.
