US not likely to change oil sanctions for now, despite Iran's nuclear rhetoric: experts

"If Tehran were to publicly acquire full nuclear weaponization, Iran's terrorist proxies like Hezbollah, Hamas and the Houthi rebels would be emboldened knowing they were backed by a nuclear equipped power, said Daniel Roth, research director at the group United Against Nuclear Iran.

"For these reasons, among others, the US should aggressively enforce sanctions now rather than at the post-nuclear armed Iran stage," he said.""
