The status of Iran's nuclear capability is surrounded by mystery even as in that is a central question in the Iran-Isreal conflict.

President Trump said Monday that he disagrees with Director of National Intelligence Tulsi Gabbard's assessment from a few months ago that Iran is not currently trying to build a nuclear weapon and has not been doing so since 2003.

Since shortly after it was founded in 1948, Israel has been intent on building a nuclear program to ensure its survival.

Iran has two known underground nuclear enrichment sites, the one Israel attacked on the first day of its assault at Natanz, and another at Fordo. Both sit south of Tehran in central Iran, but Fordo has long been the Iranian nuclear facility of most concern to international monitors and experts.

China has an estimated 600 nuclear warheads—an increase of 100 in just one year—the Stockholm International Peace Research Institute reported.

Tulsi Gabbard gave official details while speaking at the US House Congress. However, the claims have been rejected by President Donald Trump.

Only the U.S. military has the 30,000-pound bomb capable of reaching the facility and the bomber that can carry it.
