The main point Kennedy makes in his speech is about peace across nations.
Explanation:
President John F. Kennedy was successful in his inaugural address speech. He motivated the nations to come together through peace, offer friendship and companionship.
He asked the Americans to stay united and set an example for the rest of the world. He motivated people to spread freedom and justice and not war. He said that war would not lead us to anything and only staying united and bringing peace would help us succeed as a nation.
This is a SIMILE - if words such as 'as' or 'like' are used in order to compare two things (in this case, 'giant rocks with razor edges crouch LIKE a sea monster with wide open jaws'), then it is a simile.
