This attack represents a major shift, as the base falls outside the responsibility of the US Central Command (CENTCOM) and is under the jurisdiction of the US Pacific Command (USPACOM).
The distance traveled by the missile exceeds 4,000 kilometers, revealing that Iran possesses a continent-crossing arsenal that had been hidden from Western surveillance. This targeting indicates that the war zone has effectively expanded to include areas that were not part of the direct confrontation calculations.
The arrival of Iranian missiles at Diego Garcia which is a strategic stronghold for US forces far from land reflects a high level of preparedness and logistical and technical management that has surprised Western defense systems. Missiles falling in Pacific regions mean that rear bases that were considered safe and launching pads for heavy bombers are now at the mercy of Iranian fire. The attack also proves that intelligence reports about the range ceiling of Iranian missiles were misleading.
Washington is now forced to secure vast areas in the Indian and Pacific Oceans which will lead to further dispersion of air defense systems and interceptors that are already in short supply.
