WASHINGTON (Reuters) - U.S. President Donald Trump's call for a military plan to defeat Islamic State is likely to see the Pentagon revisiting options for a more aggressive use of firepower and American troops.

But U.S. officials, who spoke on condition of anonymity, doubt the country's military will advocate fundamentally changing a key strategy refined during the Obama administration: relying on local forces to do most of the fighting, and dying, in Syria and Iraq.
