No wonder the new round of talks in Moscow on the Iranian nuclear issue didn't achieve any concrete progress, frankly speaking, no one is confident of solving a matter concerning Iran's core interests through the talks. Especially as the United States has just heightened tensions by issuing new trade sanctions that include China and Singapore.

Actually, the Iranian nuclear issue is not only a matter of nuclear proliferation, it also reflects the lack of strategic mutual trust between the US and Iran. It is the US that has pushed Iran to seek to become a nuclear state, also it is the US has sensationalized Iran's nuclear program as a global issue.

In 1957, in order to compete with the former Soviet Union in the Middle East, the United States and Iran signed a civil nuclear cooperation agreement as part of the US Atoms for Peace program. In 1963, Iran signed the Limited Test Ban Treaty and in 1968 the Nuclear Non-Proliferation Treaty.
