Question

Why is there no mention of common defense in our Florida preamble

Answer 1

Answer:

The term "common defense" signify that there is a cooperative effort between two or more establishments in order to obtain a certain level of peace and security.

This is why this term can be found in the US constitution (which adopted by all the states) . It signify that the government and all the states will make a cooperative effort to maintain peace and security for the citizens.

Florida preamble is made by a single states.. The preamble did mention that the state will guarantee public order,  It's not aimed for cooperative effort between establishments. It's coming from a single establishment for its people.
