Transactions between the U.S. and Israel are not necessarily worrisome by themselves; after all, as Israel has proved, there are a host of countries willing to sell the weapons it needs. Currently, Germany is Israel's source for submarines, and if Israel really needed fighters, Russia is always looking to make a buck and always seems to have a surfeit of aircraft and other excess defense articles.
The real danger comes in Israel's habit of reverse engineering U.S. technology and selling to nations hostile to U.S. interests. Israel's client list includes Cambodia, Eritrea, Ethiopia, the South Lebanon Army, India, China, Burma and Zambia. The U.S. has most recently warmed up to India and is now in fact competing with Israel for arms sales there, but the other Israeli customers remain dubious at best.
Perhaps the most troubling of all is the Israeli/Chinese arms relationship. Israel is China's second largest supplier of arms. Coincidentally, the newest addition to the Chinese air force, the F-10 multi-role fighter, is an almost identical version of the Lavi (Lion). The Lavi was a joint Israeli-American design based upon the F-16 for manufacture in Israel, but financed mostly with American aid. Plagued by cost overruns, it was canceled in 1987, but not before the U.S. spent $1.5 billion on the project.
Last April, when the Navy EP-3E surveillance plane was forced to land in China after a Chinese F-8 fighter flew into its propeller, photos show Israeli built Python 3 missiles under the fighter's wings. If Israeli weapons sales to China induce misgivings, including the most recent U.S. blocked sale of Israel's Phalcon airborne radar, the beneficiaries of Chinese arms transfers of Israeli-American technology are even more disturbing. In 1996, as disclosed in the UN Register of Conventional Arms, China sold over 100 missiles and launchers to Iran, along with a handful of combat aircraft and warships. Even worse, in 1997 the New York Daily News reported that Iraq had deployed Israeli-developed, Chinese PL-8 missiles in the no-fly zones, endangering American pilots.
I support Israel because it is a natural ally against global Islamic terror. However, the Israeli actions w.r.t. the ChiComs are troubling. The ChiComs "String of Pearls" strategy is aimed at encircling US in Asia, Pacific, and the Indian Ocean rim.
The ChiComs are also busy signing up military deals with radical Islamic regimes....any Israeli support of the barbaric Chinese regime is essentially support of the US' greatest potential enemy. The ChiComs are the biggest threat to world peace. Period.
