According to Antiwar.com, the American taxpayers are financially propping up Israel in ways downplayed by the media of both the U.S. and Israel:

In the past 10 years alone, Americans have given Israel the equivalent of approximately $200,000 per Israeli family of five. In addition, there have been weapons subsidies, loan forgiveness programs, special trade preferences, and other generous gifts from American taxpayers to Israel. In fact, despite being one of the world’ smallest nations, Israel receives more U.S. tax money than any other country.
