While President Trump has floated the idea of a "joint venture" to manage the waterway, the White House has categorically rejected any arrangement that grants Iran a "unique economic and geopolitical position" over global energy routes. The recent temporary closure of the strait by Iranian forces on April 8 further underscores the regime’s inte...
