Firstly, the nature of it's geography and it's strategic location.
Ok, take a look at the map and see America. On one side, it's the Pacific Ocean (PO) that stretches across the world. It's hard to see how anyone would want to attack from this side given that the shortest amount of time needed to travel to across PO is 2 months. That will give enough time for America to detach the threat and be prepared. Even if countries like North Korea claim that they can shoot missiles across the world to attack America, that's sort of just a prognostication (Oh well, it's NK. What do we really expect from them right?)
On top of America, we have Canada. Oh Canada... It's Canada. Best neighbour right? Then at the bottom, we have Mexico (Yeah right, wait till they solve their own internal issues). Off America's backyard is Cuba. It's reminds me of Bay Of Pigs but well that's another story. Relationships are getting better now with Cuba, so the threat level there has decrease. Up next is all the South America countries... So technically, America is wonderfully situated in the right place.
Come on, if you don't believe in me, let's look at the next rising superpower, China. On one side, it has all the Central Asia countries and not to forget, India (Back in the 20th century they fought a war against each other). Then you have Russia. Wow. Towards the right, you have South Korea, Japan, Taiwan and Philippine around which all happens to be America's allies. Hmm..Coincident? Wait a second, did I forget about something? Oh yes, NK. Well a bad neighbour for China right? Now the Americans should learn to love and appreciate Canada.
Secondly, the way of thinking.
Who is the one who came up with the idea of racism and that it's wrong. Who fought a civil war just to that concept right? I know America is not as wonderful as it used to be but it's a land of wonder. Just take a look at silicon valley. A lot of them working there are not Americans, in fact they are from all over the place. They came to America to show people what they are capable which is not able to be depicted in their own countries. It's like a magic cast on them and as soon as they are there, their talent will be discovered in a matter of time. Everyone wants to know why but I just want to say it's a free land with opportunities. I know you may ought to differ but I don't really care.
LGBT. Who came up with this courage to tell the world that you might be just different from the norm? It's the Americans. They were one of the first few who stood up for people who are different and encouraged people to show who they really are. I'm not saying that everyone in America supports gay but they were the first people to have this idea of going against this form of discrimination and that there's nothing wrong about it.
Look at your smartphones. Who came up with up the idea of just wonderful gadgets? America. People there think way head of the world in all sense and even many scientists ended up choosing to become citizens. It's the way of thinking that shaped the country and dare to try spirit that keeps the country striving.
Thirdly, just some random examples.
Normally if you're failed at an election for presidency, you're probably end up in jail or get deported or just end up not serving the country. But who knows that a country like America would ask it's opponent to be the state of secretary? For the entire term!( a win-win situation for both parties but this is still great)
Who the heck pollutes the most? Well, America but hey, they stood for their mistake after realising that and are mending their mistake now. (Screw the republicans!) They dare to admit grave mistake they made and not afraid to tell the world their wrongdoings so that the world won't make the same mistake again.
It's hard to act as a country. America do make grave mistake like guantanamo bay, like racism, like secret tortures, like a lot of things but at the end of the day, history has proven to us that America is a great superpower in the world. A natural one. No artificial colouring or sugar involved.
