I agree.
If the goal it is defending Saudí Arabia and not to encircle Irán, to me there is no problem.
The Iranian goal it is to take out americans of the whole region. While this is not possible (EAU and Kuwait) completely, this is deffinitively a step up to take out them.
Mangekyo, you're witnessing the demise of US hegemony. And that happened thanks exclusively to Irán. They have been wiped out. And I am pretty sure that having pakistanis at the other side of the Persian Gulf will help to enhance a good neighboring and friendly relations.
Emiratis should be afraid, not persians.
