suny, while you are right about the normal generosity of the USA, and its thought for the rest of the world, this particular regime has not displayed it.
Remember, it was Bush who tore up the Kyoto Agreement, to which Clinton had agreed.
The Bush government, despite its policy of free trade for all, imposed 30% tariffs on the import of steel from Europe and Japan.
The World Trade Organisation, which polices world trade, has ruled that a tax break given to American exporters, like Boeing and Microsoft is illegal under international law and gives an unfair advantage over competing companies in other nations. The US government has so far chosen to ignore the ruling.
Companies other than those based in the USA were not allowed to tender for contracts to rebuild the infrastructure in Iraq.
Just a few examples of how this particular US administration differs from some of its predecessors.
