There are two very different categories of dangerous states in the United States: those that have become increasingly unstable through decades of war and violence and those that are now undergoing a radical change in their social and political conditions.
The first category has experienced a dramatic and significant shift in social and economic conditions over the past decade.
The second category is characterized by relatively stable social conditions, but an increase in violence and the increasing influence of foreign powers.
The difference is that while the former category is experiencing an increase of instability, the latter category is not experiencing this increase.
In fact, the last decade of the 20th century saw a decrease in violence, which has been followed by an increase.
The trend toward instability is largely the result of a combination of factors: a growing economic inequality and the political and economic chaos that has followed the end of the Cold War; a decline in support for the United State and its institutions and the increased polarization of the American electorate; and the erosion of social cohesion and democratic institutions, which are both seen as central to the survival of the United Nation.
This shift in the way that America is governed has resulted in the rise of the right-wing extremist movement and the polarization of American politics.
In short, these two different groups of states have become more dangerous.
The United States has experienced three distinct periods in its history when a large portion of the population was under threat of radicalization.
In the early 1990s, the violent protests against the Iraq war were the first wave of these movements, and it took decades of peaceful civil disobedience and the development of an effective anti-terrorism strategy for these movements to subside.
The terrorist attacks of September 11, 2001, which led to the loss of nearly two million lives and the collapse of the US government, were the second wave of the movement.
The next decade saw the rise in the use of violence in domestic political campaigns, the emergence of paramilitary groups such as the Black Panthers, and the establishment of the Patriot Act, which was used to restrict civil liberties in a way that was not limited to foreign terrorists.
The third wave of right-winger extremism began in the late 2000s and reached its peak in 2010, with the mass killing of four students at a Sikh temple in Oak Creek, Wisconsin.
This second wave, and its associated political violence, was accompanied by an unprecedented surge in the number of terrorist attacks in the country.
The Trump administration has responded by building an enormous infrastructure of anti-terror police and intelligence agencies, the largest in the history of the country, and has pursued a policy of “extreme vetting” of prospective immigrants and refugees.
These measures have made it more difficult for the country to identify people who might be a threat to American security, but the administration has also been successful in increasing the number and scope of the state-sanctioned attacks.
Although the Trump administration is not a state, the level of government and the level in which these two groups of extreme right-Wing extremism are operating has been similar over the last several decades.
The increase in violent extremism has not come from a sudden change in the politics of the states or the people in power.
It has been happening for a long time.
The last two decades have seen a steady increase in the amount of violence and terrorism in the nation.
The recent rise in extreme right wing extremism was not caused by the rise or fall of one particular political party or one particular group of states, but by a sudden shift in how the country views its own government and in how its institutions are functioning.
As I discuss in the book, the political polarization of our country has been the result both of the collapse and the rise and fall of social and democratic structures.
It was this polarization that led to an increase and continued increase in both violent and civil extremist groups.
It is also important to note that in the aftermath of the 9/11 attacks, the rise had largely subsided, but many people still felt that they were vulnerable.
The number of people who feel threatened by terrorism and other violent events, including the number who think they are at risk, has steadily increased over the years, but these threats have not gone away.
The level of violent extremism in the U.S. is now on a par with that in other countries in terms of the number it is able to generate.
While the number that is being created is not large, there is still a lot of volatility.
The political polarization that occurred in the early 20th Century had a profound impact on the functioning of American democracy and the social fabric of society.
This polarization has continued today, and even if it were to completely disappear tomorrow, the effects of the previous polarization will be felt for generations.
The same holds true for the rise, and continuing rise, of extreme-right extremism.
The violent groups that have been created by this polarization have grown to become very different from the groups that existed before the current period of polarization.
