So when your country is being invaded...you don't head the call??
I think this had more to do with wars being waged by the US and britan around the globe
I don't think you should heed the call up to fight a war in afganistan or vietnam
or some other imperialist effort
but if someone attacked US soil, you bet your bottom dollar I'd be signing up to do IT support at the Home base
I do love that couplet:
It's up to you to not heed the call up
'n you must not act the way you were brought up
