That orange dot is arabian sea entry to persian gulf connecting before strait of hormuz.If you think that orange dot is in the Persian Gulf then you are either blind, or just don't know geography?
The US officials have stated ( formally and otherwise) many times that it wouldn't be wise for the CBG to enter the strait as the IRGC navy with its swarming attacks may try to hinder carrier passage and operations, and that a fair distance from the strait in the arabian sea while launching operations is the most ideal location to be at.
