You cannot support both the Constitution and the attack in Libya.
The attack is an act of war that was never declared by Congress, contrary to Article I, Section 8 of the U.S. Constitution. In fact there has been no Congressional approval of any kind. Our Founding Fathers knew that the Executive would be tempted to send the nation into war to support his foreign policy goals, so they required that Congress specifically authorize any such actions. The fact that we have not had a declared war since World War II does not speak to changing times or the need for immediate action as much as it does the ignorance and lack of vigilance by our people.
You are also wanting in vigilance if you allow your state governor to approve the use of National Guard troops abroad, which is a violation of the same section of the Constitution, where it states that the National Guard (which was originally the Militia) is called "to execute the Laws of the Union, suppress Insurrections and repel Invasions." Our foreign wars are none of these.
If you are not vigorously opposing this action, and any other new extensions of American military presence abroad, you are part of the problem, not part of the solution to tyranny in America.
