Even though the US is considered to have the strongest military in the world, predictions can’t be made regarding whether another country can defeat the US military. As a matter of fact, the US has been in a war on terrorism for a number of years and can’t defeat ISIS or ISIL.
However, the US has a strong military due to their strong leaders, long background of history in military and their weapons and technology. With all of these, this helps strengthen the military and make them strong. They also recruit many people and the government establishes a strong budget in order to keep the military running strong. It is difficult to predict if another country can defeat the US military in a war because strategy plays an important role in a war.
