LMFAO You think we got involved with World War II because Hitler was gassing Jews? We knew what Hitler was doing from almost the beginning.
We entered WWII because of Pearl Harbor. And we only declared war on Japan at that time. After they attacked, we staked our claim to the "watchdogs for crimes against humanity" title by dropping two nuclear weapons on Japan, which led to almost half a million civilian casualties. This after massive fire bombing campaigns on their major cities, which also killed thousands of people.
We only went to war with Germany because they declared war on us first. They declared war on us in order to gain favor and help from Japan. The US never would have went to war solely because of what was happening to the Jews. We go to war for one reason and one reason only: MONEY. Either to make it or to protect it. Period.
We have the "highest morals?" Says who? Our citizens are morally conscious for the most part, but politicians run this country, and anyone with a brain knows that most of them are morally bankrupt. These are the people that represent us, and they are the "we" that you talk about.
In order for our country to be great again, we have to stop acting like it's this perfect little fairytale place where everything is right just because it's us that did it. We are moving farther and farther away from the principles that this nation was founded on. We're gradually losing the freedoms and liberties that separated us from other countries. Too many people get defensive when they hear the things that are wrong with the US. There is nothing wrong with acknowledging fundamental flaws with your country and trying to rectify them. It's a lot more patriotic than turning a blind eye while things deteriorate.
