This mindset is much like the mindset that undergirds American welfare-state programs. When the federal government is providing welfare assistance to others, it supposedly reflects how good, caring, and compassionate "we" are. By the same token, when the federal government is providing warfare assistance to some foreign regime, it supposedly reflects how good, caring, and compassionate "we" are.

Of course, nothing could be further from the truth. Foreign aid, like welfare, bears absolutely no relationship to how good, caring, and compassionate the American people are. 

It's important to keep in mind that there are two separate entities involved here: the U.S. government and the American people. They are not one and the same. There is the government and there is the citizenry.

Among the best evidence of this phenomenon is the Bill of Rights. It expressly protects the American people from the federal government. If the federal government was the same thing as the American people, the Bill of Rights would make no sense.

Thus, when one refers to actions of the federal government, there is no "we" involved. There is only the federal government that is involved. 

With the enactment of the federal income tax in 1913, the federal government acquired the power to extract a certain percentage of people's income. Through the use of this tax (and other federal taxes), the federal government acquires a vast amount of money.

U.S. officials then decide how to dispose of the large amount of money they have collected from the American people through taxation. They use some of it for foreign aid — in the form of cash or armaments to foreign regimes, including the Israeli government.
