As Claude Simon said it
"To begin with, our perception of the world is deformed, incomplete"
When I was small, I lived in the Middle East. And from my experience, people over there don't want US to interfere with their problems, unless they explicitly ask for help. No one that I knew over there had a problem with Gulf War 1, and everyone (or almost everyone) hated Saddam Hussain. They see the US trying to furthur their own interests in the region.
Then I'm assuming that most of the disagreements were based on the Iraq issue. I imagine (I'm not looking at the source of these stats) that Germany and France also have a voting record disagreeing with US.
As of the amount in foreign aid given, you are right, US gives the highest amount, but in terms of percentage of GDP, the following countries contribute more:
Norway
Luxembourg
Denmark
Sweden
Netherlands
Portugal
France
Belgium
Switzerland
Ireland
United Kingdom
Finland
Germany
Canada/Spain/Australia/Austria/New Zealand/Greece (Tied)
Japan
