Israel has received aid worth HUNDREDS OF BILLIONS of dollars over the previous decades, for such a small population and small geographical area, that is a massive amount of money.
If you translate that aid and adjusted for population and geographical size of other countries, every country in the world would become a developed country within a couple of decades.
Not just money, Israel received access to the latest technology, which helped them leap ahead in their domestic technological development because they were able to jump ahead a few steps by acquiring technology and developing a good industrial and technological base.
America even gave military aid for Israel to purchase Israeli produced military equipment, no other country in the world has received such treatment, that allows Israel to maintain and develop a good domestic military-industrial complex.
Good for Israel, but it is important to keep things in perspective.
Not a single country in the world has received such a level of support.
