Jimmuh Caatah was the first anti-American President. He was anti-American in the sense that he felt America was too big, too strong, and too successful. Carters mission was to knock America down to what he viewed as an even playing field with the rest of the world. Because we deserved it.
But, Carter considered himself an American, and never "intentionally" did anything to harm America or American allies. He did a lot, a whole lot, of damage to America and the world, but it was because of stupidity, and his simpleton view of the world.
Obama never considered himself to be an American or even an American President. Obama considered himself to be outside of the province of America, or American history and culture. He viewed his term as President as if he was a U.N. President appointed to oversee the international global region known as America.
Carter wanted to 'correct' America. Obama wanted to 'punish' and 'damage' America. That is the difference.
Obama was not the first anti-American President, but he was the first American President to actively support our enemies while deliberately undermining America and her allies. I firmly believe that the reason Obama attacked Libya is because Ghadaffi was on the verge of becoming a formal Western ally. And Obama could not allow that to happen.
Yeah, Obama is a subversive agent in term of Western nations. Handing him the keys to the White House was tantamount to national suicide. Fortunately, Obama is bungling and not very bright. And he is extremely arrogant and lazy. If not for him spending so much time partying and 'on vacation', although he did considerable damage to America and to the world, he could have done much more damage than he did.
Overall, we got out of the Obama Presidency with manageable damage, taking into account what he could have done if he was an intelligent, motivated, normal person. Thank God Obama is as lazy as he is. That saved America and the world a lot of grief.
