“The Obama administration is considering dropping the president’s commitment to withdrawing all US troops from Iraq by the end of the year in favor of keeping several thousand military trainers there.

The plan is already running into roadblocks in Iraq and in the US. In Washington, some political leaders are calling on President Obama to leave no troops behind, while others say the president should heed his military commanders on the ground and keep far more troops than the 3,000 to 4,000 he is considering.”
