Finally we come to the financial argument, namely that the US gives an inordinate amount of money to Israel -- too exorbitant a cost that is out of proportion to what the US gets in return. In fact, the United States spends much more on its military bases in the Arab world, not to mention on those in Europe or Asia, than it does on Israel.
Israel has indeed been very effective in rendering services to its US master for a good price, whether in channelling illegal arms to central American dictatorships in the 1970s and 1980s, helping pariah regimes like Taiwan and apartheid South Africa in the same period, supporting pro-US, including Fascist, groups inside the Arab world to undermine nationalist Arab regimes, from Lebanon to Iraq to Sudan, coming to the aid of conservative pro- US Arab regimes when threatened as it did in Jordan in 1970, and attacking Arab nationalist regimes outright as it did in 1967 with Egypt and Syria and in 1981 with Iraq when it destroyed that country's nuclear reactor.
While the US had been able to overthrow Sukarno and Nkrumah in bloody coups, Nasser remained entrenched until Israel effectively neutralised him in the 1967 War. It is thanks to this major service that the United States increased its support to Israel exponentially. Moreover, Israel neutralised the PLO in 1982, no small service to many Arab regimes and their US patron who could not fully control the organisation until then. None of the American military bases on which many more billions are spent can claim such a stellar record.
Critics argue that when the US had to intervene in the Gulf, it could not rely on Israel to do the job because of the sensitivity of including it in such a coalition which would embarrass Arab allies, hence the need for direct US intervention and the uselessness of Israel as a strategic ally. While this may be true, the US also could not rely on any of its military bases to launch the invasions on their own and had to ship in its army. American bases in the Gulf did provide important and needed support but so did Israel.
