Israeli Defense Minister Yoav Gallant began on Thursday an official visit to Greece and Cyprus, revealing significant progress in Tehran’s nuclear program during a stop in Athens.

“While one Iranian arm spreads weapons and [terrorist] proxies, the other continues its program to obtain nuclear military capabilities. And make no mistake—Iran will not be satisfied with a single nuclear bomb. So far, Iran has gained material enriched to 20% and 60% for five nuclear bombs,” said Gallant.
