Where in U.S. law does it state that our government has a responsibility for our national defense?

one of the duties specifically delegated to the Federal Government is to "Provide for the common defense".

Preamble of the Constitution.

Article 1 - The Legislative Branch

Section 8 - Powers of Congress

The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;

To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water;

To raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years;

To provide and maintain a Navy;

To make Rules for the Government and Regulation of the land and naval Forces;

it's in the Preamble: We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.

That is a passing mention.

In section 8, you'll find as much detail as they go into.

[The Constitution of the United States]

[Article. I.]

[Section. 8.]

[The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;]

The Constitution...

Study it.

The first paragraph...

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.

Read the U.S. Constitution. ALL of it. You obviously haven't EVER read it, or you'd be able to answer your own question.

Btw, Article 1, section 8. Read it.

You would be a perfect fit for the Obama administration!

You must be majoring in Constitutional Law, right?

It's in the preamble of the constitution. I memorized it back in 5th grade

well technically they have the responsiblility of setting up the defense and as we are responsible on paying taxes and voting how it should happen. power to the people.

Dude. I don't care if it says it has the responsibility or not.

I want a strong defense.
