i'm not fully understanding the strategery involved in trying to take kharg island

12. Ummm, it's a Trap?

Okay, it's a nice to capture due to its functional usefulness to Iran, but it's also in a killing zone covered with explosively flammable facilities.
I wouldn't put it past Iranian hardliners to decide they could make a huge, dramatic statement concerning their resolve and decimate US Marines in the process.
The Iranians understand Chess, they've developed and played versions of it for millennia.
I think landing on Kharg Island has far less value to it than, say, moving in from Pakistan and securing a hundred or so miles inland before taking it and settling out folks or infrastructure on it for the Saudis or Omanis.
