Marine Corps Gen. James N. Mattis, who heads U.S. Central Command, won White House approval late last year for the deployments of additional troops and warships to the Persian Gulf to deal with Iran and other potential threats.
The Pentagon has stationed nearly 15,000 troops in Kuwait, including a small contingent already there. The new deployments include two Army infantry brigades and a helicopter unit, a substantial increase in combat power after nearly a decade in which Kuwait chiefly served as a staging area for supplies and personnel heading to Iraq.
The Pentagon also has decided to keep two aircraft carriers and their strike groups in the region.
(So, this has been previously decided. "Won approval late last year...")
