The Pentagon has denied reports of sending 10,000 additional combat troops to West Asia, but new reports suggest Washington is reviewing major military buildup options amid escalating tensions with Iran. Officials say the deployment would provide more military flexibility if diplomatic talks collapse. The Wall Street Journal reports that the potential force could include infantry and armored units, adding to thousands of U.S. Marines already deployed in the region. At the same time, the Pentagon is studying “final blow” scenarios including a massive bombing campaign and possible ground assault.
