How does the Military Defend the Right to Free Speech?

The military defends our constitution against all enemies, both foreign and domestic. Our enemies in the world would do away with our Constitution. In the case of the Taliban, al-Qaida and other extremist organizations, they would force us, or scare us into accepting their brand of extremist views and have us do away with our constitution in order to accept their legal system. The U.S. defends the rights of the Constitution by keeping them over there instead of having them come to our shores. It is far better to fight your enemies on their homeland than to defend ourselves on our own homeland. There is a lot more to the discussion than defending the homeland by engaging our enemies overseas. Our military forces are charged to "defend the Constitution of the United States against all enemies, both foreign and domestic". That means the military forces are charged to prevent an overthrow of the Constitution whether ot is from a faction within the United States, a group within the government or an outside enemy. In short, the Constitution charges all who put on the uniform to take an oath that swears us to make sure the Constitution remains the supreme law of the land, no matter what. That is why our government and legal system cannot be overthrown by a coup or the law ignored by either a hostile force, such as the American Communist Party during the 1920-1930 time frame, the German American Bund in the 1930-1940 time frame or by the government should it take such liberties and abuses. If, for example, the government pass a law outlawing free speech, for example, then the Supreme Court has the authority to suspend the government and take charge of the military in order to enforce the Constitution over the legislature, restructure elections and get the country back on track according to our laws. How we defend the Constitution in regards to the war on terror is by keeping the enemy engaged far away from our shores.
