There is no denying that US has in its history helped other nations of the world. I find it admirable that US, France AND Britain airlifted tons of aid to Berlin when Russia blocked all land access to it. This was soon after the second world war where thousands of Allied soldiers died fighting the Germans.
US has also contributed immensely to aid around the world since then. It's achievements in science and technology is also remarkable. I am grateful for it's contributions to the world.
But America is not without it's dark spots. When people talk about American arrogance, it's mistakes that it has yet to recognize, or apologize for, they are talking about something substantial.
In 1953, to further Western interests, Americans played a hand in removing the democratically elected ruler of Iran.
US has held a relatively unwavering support of Israel over the entire land conflict. Regardless of what side of the debate you are on, consistently supporting one side with money, arms and political support for an issue that is anything but simple gives of an impression of partiality.
In 1988, a passenger jet was shot down by an American ship. As of today, there has been no apology.
The CIA funded and trained thousands of Afghans to fight the Soviets. At the conclusion of the war, when the Afghans defeated the enemy of the Americans, the money to rebuild was no where to be found. The fighters who were so willingly trained now had no home to go to, and no money to replace it.
These are just a few events that people in the other part of the world remembers when they think of America. If you think America is guilt free, then you are sorely wrong. Yes, other countries in the world have done a lot of crap, their hands have blood on them. But when you think of the global reach that the world's super power has to a country like Egypt or Iran, then you have less people affected by their actions.
And as for arrogance, when US-UK marched into war in Iraq with false assumptions, while France and Germany resisted, I remember outrage that the French could betray a country that saved them. French fries were now freedom fries, French wines were poured down the drain, a country that decided to listen to it's own populace and make it's own decision was now the betrayers?
Like cbtboyuk said, a little humility doesn't hurt. In fact, it can help your standing in the world. What good is a expensive military if you aren't liked in the world?
As for Obama, hate or love his domestic policies, but his foreign is much better then what I've seen in the last decade. I used to know so many people who had nothing but respect for the USA. Two wars later not so much.
