an army like the american one could conquer that area and the neighbouring regions in no time and with little effort;
US military is one of the weakest militaries in the world that has been starting war after war and losing all of them too because it is weak and corrupt. They neither have the fire power, nor the numbers nor the technology to win any wars. They are stuck in the 20th century. The only thing
American terrorists are capable of is murdering civilians. Nothing else!
To face a super power like Iran on the ground, the weak US regime would require at least 1.5 to 2 million troops. Something they don't have. And that number is to just begin an invasion.
Majority of those forces would be vaporized in the first week.
As a matter of fact back in March this year the US regime tried to have boots on the ground inside Iran 2 times only.
The first time they were trying to invade from 2 fronts, first was from Kuwait's Bubiyan Island to take over the closest target in Iran which was Abadan's refinery and the second was from Emirates to take the closest and smallest Islands.
With the dominance Iran has over the entire region, the plan was found before they could even mobilize and Iran bombed them while they were preparing to launch the attack eliminating at least 600 of the Epstein Axis terrorists and sank 6 of their vessels in a blinking of an eye.
