Calls for U.S. troops to fight Islamic State misguided, say experts

WASHINGTON (Reuters) - Americans want the Obama administration to get tougher with the Islamic State following the carnage in Paris, but many of the measures now being proposed could actually make the threat worse, counter-terrorism experts said.

Republican presidential candidates, lawmakers and others are calling for deploying U.S. ground forces to the Middle East, using air power to create a Syria safe zone to train anti-Islamic State fighters and barring Syrian refugees.
