Export Ban On Israeli Early Warning System to Korea

Is this another sign of the distrust the US government has with Korea?:

Korea’s much delayed plan to buy airborne early warning systems, the so-called E-X project, has hit another snag in the form of communications equipment in the favored bidder’s aircraft that falls under an export ban by U.S. authorities. The G-550 by the Israeli firm IAI Elta was said to be the favored of two remaining systems in the latest bidding round, pitted against the reportedly more expensive E-737 by U.S. aerospace giant Boeing. But with no U.S. export authorization for the Israeli equipment in sight, the W1.8 trillion (about US$1.8 billion) E-X project could be delayed again.

The article makes this issue out to be some kind of sinister plot by the US government to make Korea buy the Boeing aircraft, however they couldn’t buy the Boeing aircraft either because it has the same technology. So what technology is in the aircraft that is so sensitive?:

The equipment in question consists of five items including Data Link (link 11 and 16) discerning aircraft, IFF (Identification Friend or Foe), SATCOM, UHF/VHF Have Quick Radio, and GPS P(Y) code technology.

These system are extremely sensitive because the different data links are what provide air picture and communications for US forces. This technology would be a bonanza for the US’s military enemies and competitors. So the decision by the US to stop the Israelis from selling the technology to Korea is a sure sign that the US government does not trust Korea to keep the technology secret from the likes of the North Koreans, Chinese, and Russians who are all in the area.
