Currently (May 11, 2014) the US is not involved in any declared wars, and hasn't been since August, 1945.
The only active conflict is the ongoing "war on terror", in which American soldiers and airmen are fighting Islamic terrorists in Yemen, Afghanistan and Iraq.
Over the past 200 years, there have been many military conflicts and wars that the US did not participate in.Crimean WarRusso-Japanese WarFranko-Prussian War
If you mean the northern states, they fought in the Civil War. Other than that one time, the US has always been united. Any wars which involved the north, involved the entire US. The US has, of course, fought in two world wars and many other wars.
Throughout the 20th century, the United States was involved in several significant wars, including World War I (1917-1918), World War II (1941-1945), the Korean War (1950-1953), the Vietnam War (1955-1975), and the Gulf War (1990-1991). Additionally, the U.S. participated in numerous military interventions and conflicts during this period, such as those in Grenada (1983) and Panama (1989). Overall, the U.S. fought in at least five major wars, along with numerous smaller conflicts and operations.
The two major players in the Cold War were the US and the Soviet Union. These two nations did not have battles or real wars during the Cold War years. Other conflicts among smaller communist nations, and a large one, China, were related to the Cold War. Wars in Korea and Vietnam can be considered wars with roots in the Cold War.

No, not at all. Many conflicts have been solved without war. History remembers the wars, but the almost-wars are less memorable, to say nothing of the conflicts which have been settled without even the threat of war. For example, there was a conflict between the US and Great Britain in the 19th Century over where to draw the US-Canadian border, and although there was some talk of war, it never happened.
Yes. There was no US formal declaration of war, but there was US military involvement, so they are considered "conflicts" in US jurisprudence. However, for the Iraqis, Vietnamese, and Koreans, they were certainly wars.
There are several major Middle East Conflicts. You may have to be more specific in your question to get answer better than, some have ended and others have not. (It would be like asking "Did the US win the war?". The US fought in many distinct wars, so the question is only answer that US won some wars - American Revolution and lost some wars - Vietnam.)
They have made conflicts (wars) between major powers such as the US and Russia very unlikely. The cycle of major wars that plagued Europe for centuries has also stopped. Hopefully this will continue, but conflicts over dwindling natural resources may eventually arise.
There were several wars going on in 1812- which one are you referring to, the Independence struggle in the US, or Napoleon's expansionist conflicts in Europe?
Vietnam War - LostBeirut - LostSomalian Wars 1,2 AND 3 - All LostRed Clouds War - LostWar on Terrorism (2001-present) ALL of these are still active,but dont look like it will ever be a Victory,so this will be 3 more lost wars for the US.2.12.1 Afghanistan2.12.2 Philippines2.12.3 Iraq
The Neutrality Acts of the 1930s passed by the US Congress is an example of how the US attempted to stay out of European conflicts. The US would eventually participate in both World Wars.

He warned about foreign alliances that could draw the US into expensive trade conflicts and even wars.
