What I get from it about soldiers in general and their families and 9/11 and the war:

And you choose to break our families
Tell me you've used all precautions known
And I'll stand beside the ones who stood alone
How long will we have to sing until you finally bring our sons, our daughters home?
We'll let the prayers start healing, what time's been stealing

also consider this:

We've lost respect for decency
When one can turn our world into an ant pile
We run circles, no direction do I see
The dust has blinded you, the dust has blinded me

as in 9/11 the towers also have you ever seen a kangaroo cry? Google it it's the saddest animal pictures I've ever seen...

Stop the war bring our boys and girls home and 9/11 in a nutshell
