Concept note-1: -THE SPANISH-AMERICAN WAR in 1898 was America’s shortest war lasting just 10 weeks.
Concept note-2: -Only 15 years out of the entirety of the 244 years the United States has been in existence have been peaceful. Only 15 years without conflict.
Concept note-3: -When was the last time the US won a war? Since 1945, the United States has very rarely achieved meaningful victory. The United States has fought five major wars-Korea, Vietnam, the Gulf War, Iraq, Afghanistan-and only the Gulf War in 1991 can really be classified as a clear success.
