Good God this is wrong on so many levels.
Who does the world seek out for help when there's:
Famine
Flood
Disease
Earthquakes
the United States...
Who has Europe called for help when the forces of Totalitarianism threatened?
You know the answer.
Ppl bitching about the US should look at our history and how good we have been to the world in the past 200+ years.
Where was the USA when Hitler was marching through Europe? It was content to sit by on the sidelines and didn't enter the Eurpean theater until Hitler declared war on the USA.
Yes I know all about lend-lease, US ships escorting covoys part way across the Atlantic prior to the USA formally entering the war, but that was the due to actions of a few esp. FDR.
But lets go back a bit further and the USA's treatment of the native American's, not the best chapter in the USA's history is it?
There is no doubt that the USA has done some good, but the picture is not as rosey as you are making it to be. The same can be said of many countries that they have done some good things and some not so good things.
And I think you'll find lots of nations help out when it comes to famine/disaster etc...
