The United States and Israel's special relationship is good for both of their economies. When they are trade partners as close as they are, their economies become stronger and the global trade market is boosted up significantly from each countries' large volume of trade, which also increases the countries' PPP.
The United States has always provided significant economic support to Israel because of our long-standing friendship, because of Israel's strategic location in the Middle East, and because Israel is the homeland of Judism and Christianity and as a nation, represents values which we hold in common. However, it also has a strong economic component. 74 percent of U.S. aid given to Israel for defense has to be spent with American companies and it is mutually beneficial for this relationship to continue.
