Tomorrow the permanent five members of the UN Security Council and Germany meet with Iran in Geneva to discuss Iran's nuclear program.
Many believe the only way to convince Iran to become forthcoming about its nuclear intentions and truly abandon any nuclear weapons aspirations is for there to be solidarity between all six nations. But there's concern about whether Russia and China will hold fast with the United States, the UK, France and Germany.
Tougher sanctions may be on the horizon but not if Russia and China balk. And if they do, Iran may interpret this as a green light to develop nuclear weapons.
President Obama has said he favors a diplomatic approach toward Iran but has not taken the military option off the table. But without the support of Russia and China, the United States - or Israel - face the prospect of international condemnation should they eventually take action without Security Council approval.
Joining us on News Talk Online on the Paltalk News Network at 5 PM New York time Thursday will be Leonor Tomero, director for nuclear non-proliferation at the Center for Arms Control and Non-Proliferation.
