How good an ally is Israel?

A Passover Hymn (Da'ye'nu) 2011, about US-Israel relations, from Ambassador (ret.) Yoram Ettinger, Jerusalem, Israel:

"How many degree of beneficence hath the Almighty conferred upon us?!  If He had brought us forth from Egypt, and had not executed judgment upon the Egyptians, it would have sufficed (Da'ye'nu)...

If He had inflicted justice upon them..., it would have sufficed (Da'ye'nu')..."

If Israel were merely the most effective battle-tested laboratory available to the USA, the source for over 600 modifications of the F-16, and thousands of cutting-edge modifications in hundreds additional US military systems, enhancing US national security, while providing the US defense industries a unique mega-billion dollars competitive edge in the global market, expanding US employment, research & development and export infrastructures - Da'ye'nu (it would have sufficed to crown Israel as a unique two-way-street ally of the USA);

If Israel were merely the source of breakthrough battle tactics, which were the first to penetrate/jam/destroy the most sophisticated Soviet/Russian surface-to-air missile batteries and radar systems, in addition to transferring to the US the first Soviet MIG-21 and 23 and other Soviet military systems, which tilted global balance of power in favor of the USA, providing the US defense industries with mega-billion dollars bonanza - Da'ye'nu;

If Israel were merely the source of intelligence - shared with the USA - which exceeds the scope of intelligence received by the US from all NATO countries combined (according to Senator Daniel Inouye, former Chairman of the Senate Intelligence Committee and current Chairman of the full Appropriations Committee) and is equal to five CIAs (according to retired General George Keegan, former Chief of US Air Force Intelligence) - Da'ye'nu;

If Israel were merely the country which destroyed Iraq's nuclear reactor in 1981 (in defiance of global opposition), thus providing the USA a conventional option in  the 1991 Gulf War, sparing the US a potential
traumatic nuclear confrontation -  Da'ye'nu;

If Israel were merely a source of battle-proven experience and military systems - combating IEDs, car bombs, suicide bombers and generic terrorism - shared with US Special Operations units, which battle Islamic terrorists in Iraq and Afghanistan, thus minimizing US losses - Da'ye'nu;

If - as stated by the late General Alexander Haig, former Supreme Commander of NATO and former Secretary of State -Israel were merely the largest American aircraft carrier which does not require a single American personnel, which cannot be sunk, which is the most battle-tested and cost-effective, and located in a region, which is critical to vital US economic and national security interests - Da'ye'nu;

If there would not be an Israel in the eastern flank of the Mediterranean, and the US would have to deploy to the region real aircraft carriers with tens of thousands of American servicemen, costing the US taxpayers $20BN annually and possibly dragging the US into local and regional conflicts - all of which has been spared by the existence and capabilities of the Jewish State - Da'ye'nu;

If there would not be havoc in Arab lands, highlighting the Jewish State as the only stable, reliable, credible, capable, predictable, democratic and non-conditional ally of the USA - Da'ye'nu;

If Israel were not the place where- according to Warren Buffett - hundreds of  major American companies and investors shop for innovative ideas, which they transform into technologies, products and manufacturing lines, benefitting both American and Israeli employment, trade, research & development and exports - Da'ye'nu;

If Israel were not the source of hundreds of revolutionary medical device, healthcare, telecommunications, Internet, laptops, cellular and social networking technologies/products.- enhancing quality of life in the US and throughout the globe - Da'ye'nu;

If US-Israel covenant were not uniquely based on shared values (dating back to the Pilgrims and the US Founding Fathers), joint interests and mutual threats - Da'ye'nu (It would have sufficed to crown Israel as a unique two-way-street ally of the USA).
