Well...no. The NSA has no domestic mission and is not allowed to operate domestically unless Americans are tied to terrorist suspects overseas, for starters, neither does the CIA, and saying that the army is not allowed to operate within domestic boundaries just isn't true. If the security of the homeland is threatened then they absolutely do. How else do you explain the Union response to the Civil War? The military exists to defend the nation. If the nation is threatened at home, then that's where they are going to be.
In the case of the Civil War, The Confederate States Of America was a sovereign nation, with its own President and congress, duly elected, its own laws and Constitution, its own currency, and was recognized as such in the international community. It was even recognized as a sovereign nation by the United States, since war was formally declared against the Confederacy after the bombardment of Fort Sumpter. It was NOT a part of the Union, since every member State had formally withdrawn from the Union. We might argue about who started the war and why, but all of the action seen by the Union Army was in the Confederate States, not the United States, therefore they were not operating within national boundaries. A technicality, I agree, but nonetheless a fact.
Otherwise, you are correct. Under certain (extreme) conditions, the President may order Federal troops used to quell local disturbances. The first example of this that I can recall was when Alabama Governor George Wallace ordered the Alabama State Militia to prevent integration activities by black Americans and their supporters. The President simply Federalized the Militia, putting them under his own command, and ordered them to protect the protesters from local violence. That was a case of Federal troops operating within the United States.
