"National security" is the cloak that the executive branch uses to make certain that the US government is unaccountable.

Without accountable government there is no civil liberty and no democracy except for the sham voting that existed in the Soviet Union and now exists in the US.

There have been periods in US history, such as President Lincoln's war to prevent secession, World War I, and World War II, when accountable government was impaired. These were short episodes of the Constitution's violation, and the Constitution was reinstated in the aftermath of the wars. However, since the Clinton regime, the accountability of government has been declining–for more than two decades, longer than the three wars combined.

In law there is the concept of adverse possession, popularly known as "squatters' rights." A non-owner who succeeds in occupying a piece of property or someone else's right for a certain time without being evicted enjoys the ownership title conveyed to him. The reasoning is that by not defending his rights, the owner showed his disinterest and in effect gave his rights away.

Americans have not defended their rights conveyed by the US Constitution for the duration of the terms of three presidents. The Clinton regime was not held accountable for its illegal attack on Serbia. The Bush regime was not held accountable for its illegal invasions of Afghanistan and Iraq. The Obama regime was not held accountable for its renewed attack on Afghanistan and its illegal attacks on Libya, Pakistan, and Yemen, and for attacks by its proxies on Syria.

We also have other strictly illegal and unconstitutional acts of government for which the government has not been held accountable. The Bush regime's acts of torture, indefinite detention, and warrantless spying, and the Obama regime's acts of indefinite detention, warrantless spying, and murder of US citizens without due process. As the Obama regime lies through its teeth, we have no way of knowing whether torture is still practiced.

If these numerous criminal acts of the US government spread over the terms of three presidents pass into history as unchallenged events, the US government will have acquired squatters' rights in lawlessness. The US Constitution will be, as President George W. Bush is reported to have declared, "a scrap of paper."
