Iran is reportedly ramping up military preparations on Kharg Island, a critical hub for its crude oil exports, amid growing speculation of a potential US ground operation. According to reports, Iran has deployed additional troops, lined parts of the island with mines, and strengthened air defence systems in anticipation of possible escalation. The developments come as thousands of US Marines are believed to be moving towards the Persian Gulf. While there is no official confirmation from Washington, analysts warn that any ground operation in the region — particularly on heavily fortified terrain — could be extremely challenging and costly. As tensions mount, Kharg Island has emerged as a potential flashpoint in an already volatile West Asia conflict.
