At a time when U.S. and Israeli officials are increasingly considering the heavy burden of having to attack Iran’s nuclear weapons related facilities, China’s sale of the J-10 to Iran may signal the beginning of a deeper Chinese effort to protect Iran’s nuclear aspirations, much as it has ensured North Korea’s nuclear weapons development. The J-10’s defensive capabilities would be formidable, as would its ability to perform all-weather strikes with new precision guided weapons against Israeli or U.S. targets. For Israel a J-10 sale to Iran would mark a sobering betrayal of Israel’s considerable efforts to help China’s military modernization, to include its substantial help with the J-10 program, and one of its air-to-air missiles, both of which may apparently arm Iran.

Israel contributing to the Great Beast's armory? How ironic.

So Dick (and Haliburton) were not the only ones to help Iran with their nuclear developments.

1957 The United States and Iran sign a civil nuclear co-operation agreement as part of the US Atoms for Peace program.[2]

9 August 1963, Iran signs the Partial nuclear test ban treaty (PTBT) and ratifies it on 23 December 1963.[3]
