In his most significant military decision to date, President Obama has ordered an additional 17,000 US troops to Afghanistan. The move fulfills a campaign pledge to increase the size of the US occupation. The new deployments will take effect in May, increasing the US occupation force to 55,000 — a 50 percent rise. Another 32,000 non-US NATO troops are also in Afghanistan. The news came as the UN said Afghan civilian casualties jumped by nearly 40 percent last year. US-led forces were responsible for nearly 40 percent of the deaths, killing 828 people out of a reported 2,100 casualties.
