Israel & the USA common. And how does the USA benefit
from the relationship:

Israeli private & Corporate industry have invested $19 Billion
dollars (Low Estimate) in the USA economy.(USA Library of Congress )

The 2.7 Billion aid received by Israel from the USA must be in
large used IN THE USA for purchases, thus creating 100.000 American jobs.

Jews and Jewish owned Corporations in the USA pay an estimated
200 Billion Dollars in tax to the IRS.

The USA in it's post 1973 Yom Kippur war, and in an
effort to bring 'peace' to the region, offered Israel & Egypt
3 Billion each IF they agreed to a peace agreement, later
when ''peace'' was signed the USA stood by it's commitment.

How does the US benefit from Israel's military industry? Here's a sample:

The above outlying only some of the ways the US directly benefits from its alliance with Israel in maters of national security - there are countless joint venture between Israeli firms and US firms that touch the daily lives of every US citizen - from the computers you use to the cars you drive - they would be not perform nearly as well without the R&D of Israeli high tech companies.
