Israel is the only western-oriented democracy in the Mid-east, but I agree with you.
They are already a strong nation because they are educated, civilized and technically advanced. They can survive without our money. Besides, what will they do when Fed.gov ultimately goes bankrupt?
You raise a good question.
Ultimately, the lavish aid program is weakening Israel, in all sorts of invisible ways, and will lead to destabalisation. Aid and hand outs always lead to corruption - the money goes in all directions. Israel was a much more strong, dynamic country in its more austere days of the 1950s and 1960s. Oddly, they had no aid back then.
One day, the gravy train will halt. The results will be more upheaval.
