U.S. President Donald Trump’s administration is weighing a deployment of up to 1,000 American soldiers to Kuwait to serve as a reserve force in the fight against Islamic State as U.S.-backed fighters accelerate the offensive in Syria and Iraq, U.S. officials told Reuters.

Proponents of the option, which has not been previously reported, said it would provide U.S. commanders on the ground greater flexibility to quickly respond to unforeseen opportunities and challenges on the battlefield.

It would also represent a step away from standard practices under President Barack Obama’s administration by leaving the ultimate decision on whether to deploy some of those Kuwait-based reserve forces in Syria or Iraq to local commanders.

“This is about providing options,” said one U.S. official, who spoke on condition of anonymity.
