but it's your duty to your country.

If the war comes to American soil I will stand up and I will fight but this whole overseas business what is it?

And I honestly thought it was illegal to not register for the draft once you were 18?

It is, if the government should choose to take action I could go to jail.

Register and during the registration you can make note of being a conscientious objector

Here in the U.S you can only apply for C.O status if you're called in for service, they can turn you down, and they don't exactly tell you that you can apply when you're notified. There's also a deadline but basically they make it difficult to get C.O status.
