Declaration of Independence
by Thomas Jefferson (adapted excerpt)
Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of
Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the
establishment of an absolute tyranny over these States. To prove this, let facts be submitted to a candid world. He has endeavored to prevent
the population of these States; for that purpose, obstructing the laws for naturalization of foreigners: refusing to pass others to encourage their
migrations hither, and raising the conditions of new appropriations of lands. He has obstructed the Administration of Justice, by refusing his
Assent to Laws for establishing Judiciary powers.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
