Right now, it is my war!
The American government is on TV 24/7 warning us that terrorists are in place here, and planning and waiting to kill us all with biological weapons of mass destruction!
If this administration can not protect its citizens inside America, and it didnt on 9-11,then it wont matter about wars offshore, because we will all be dead!
Countries do not ally with each other because they "like" each other or prefer one another. They ally with each other because they have a common interst.
The structure of a country's political regime has nothing to do with whether it has a common interest with us or not. The Cold War is over.
