The most important was the American Revolutionary War leading to the Declaration of Independence, the 2nd  was the Civil War which preserved the Union and the Third, we are living it in real time. We have a President out to destroy the United States, he has bowed to tyrants, extends his hand to dictators and no wants to use NASA to improve relations with Muslim nations. What, we may ask, why are you committed to improving relations with countries like Egypy and Iran who stifle free speech, treat women like dogs and control the press. Can you President Obama give us a logical answer?
