Throughout the entire history of america, every single president has publicly and repeatedly professed a fervent belief in and devotion to god. In fact, I don't think you will find a single regularly scheduled presidential speech during the past 50-100 yrs, in which the president failed to mention god at least once. Most common is the sign-off at the end of the speech, of "god bless america", or "god bless you all". Your supreme leader, who actually exists, is pretending that god exists, that america and thus all of it's citizen-slaves, need to be supported and blessed by an even greater supreme leader, and of course the only way to gain god's blessing is to believe in him, pray to him, and obey him. Not only does the president gleefully seize upon every opportunity to promote the insane god myth, but being the supreme "human" leader, by aligning himself with god in every public speech, everything that the president says is put forth as if channeled directly from god, this is the obvious ploy that is used here. By concluding his speech with "god bless america", the president is saying: "I am one of your two supreme leaders, and everything I have said in this speech has the blessing and support of your other supreme leader, the god who you worship and who you must remain faithful to in order to gain an eternity of heavenly bliss when you die. In blindly supporting me, my policies, and america, you gain the blessing of god." He doesn't need to say this out loud, the message is clear and undeniable, and embraced by a great many hopelessly brainwashed and societally/religiously addicted citizen-slaves. Within toxic and diseased societies, no aspiring societal leader who refuses to fervently proclaim a strong belief in god has any chance of ever attaining the presidency or any other national-level position of power, because of the fact that the vast majority of all citizens within the society are hopelessly addicted to the insane god myth and will only allow someone who validates the delusion that they have built their lives around, to become their empowered leader. Remember, citizen-slaves will always insist upon their leaders at least pretending to reflect and mirror the delusions, perversions, and insanity that they themselves are addicted to.
Look at the american pledge of allegiance. The pledge reads: I pledge Allegiance to the flag of the United States of America and to the Republic for which it stands, one nation under God, indivisible, with Liberty and Justice for all
This pledge is a toxic instrument of mental/intellectual brutalization, specifically targeted at children. All children are taught the pledge of allegiance, told that it represents important, valuable, Truth, and ordered to publicly proclaim this pledge, usually on a daily basis, within the school system. The phrase "one nation under god" not only is designed to infect children with the toxic notion that god exists, but even more perversely, to convince the child that he must be subservient to the god creature. The pledge says that the entire nation, thus all citizens, are under god, this means beneath god, less important than god is, obligated to obey and follow the will and decree of god, etc
They are confronted with the toxic message that an invisible, non-existent entity is in fact their "boss", more important than they are, and must be blindly and insanely believed in, worshipped, and obeyed. Interestingly, the original pledge of allegiance had no direct mention of god in it. Only several centuries later, in 1954, did the genocidally evil supreme leader of america, then president Dwight D. Eisenhower, sign into law a constitutional amendment that very specifically added just two words, "under god", to the pledge. As he signed this new law, in explaining why the two words were being added, your evil supreme leader declared: "In this way we are reaffirming the transcendence of religious faith in America's heritage and future; in this way we shall constantly strengthen those spiritual weapons which forever will be our country's most powerful resource in peace and war." Don't you just love how brilliant your evil leaders are, in delivering toxic decree under a flowery verbal guise of benevolent-sounding eloquence? If he were being honest and truthful, Dwight would have said: "I feel that terroristically forcing all american children to pledge that they believe in god will result in future generations of citizen-slaves being more heavily addicted to this insane myth, thus making it easier for future american leaders to get all citizen-slaves to blindly support their evil policies as well as to get more young people to willingly sacrifice their lives upon command of societal leaders."
