WASHINGTON  — A new military strategy to meet President Donald Trump’s demand to “obliterate” the Islamic State group is likely to deepen U.S. military involvement in Syria, possibly with more ground troops, even as the current U.S. approach in Iraq appears to be working and will require fewer changes.

Details are sketchy. But recommendations due at the White House today are likely to increase emphasis on nonmilitary elements of the campaign already underway, such as efforts to squeeze IS finances, limit the group’s recruiting and counter IS propaganda that is credited with inspiring recent violence in the U.S. and Europe. One official with knowledge of the recommendations said the report would present a broad overview of options as a starting point for a more detailed internal discussion. The official wasn’t authorized to speak to reporters about the contents of the document and demanded anonymity.
