In the excerpt the “four freedoms” speech, why does roosevelt see the present threat to american security and safety as unprecedented

The "Four Freedoms" Speech was the 1941 State of the Union address. The nickname comes from the four freedoms outlined by Franklin D. Roosevelt, which he argued all people deserved (speech, worship, want and fear).

The speech defended a policy of intervention in WWII, which was a significant break from previous foreign policy. He argued that the threat to America's security was unprecedented, and therefore, required strong action. He claimed that:

"It is true that prior to 1914 the United States often had been disturbed by events in other Continents. We had even engaged in two wars with European nations and in a number of undeclared wars in the West Indies, in the Mediterranean and in the Pacific for the maintenance of American rights and for the principles of peaceful commerce. But in no case had a serious threat been raised against our national safety or our continued independence."

the apollo program, also known as project apollo, was the third united states human spaceflight program carried out by the national aeronautics and space administration (nasa), which succeeded in landing the first humans on the moon from 1969 to 1972.
