Washington, Aug. 21 : Despite President Barack Obama''s attempts to prepare the American people for rising casualties in Afghanistan, a new poll shows most Americans see the war as a wasted effort.

The Washington Post-ABC News poll showed 51 percent of people say the war is not worth fighting. That sentiment was particularly high among members of the president''s own party, with seven in 10 Democrats saying the war is not worth its costs.

Obama on Thursday again argued that U. S. forces need to commit themselves for the long haul, acknowledging that the influx of U. S. troops in the country has coincided with a sharp increase in casualties.

The poll of 1,001 adults was conducted Aug. 13-17. It had a margin of error of 3. (ANI)
