Republican presidential candidate Mitt Romney is trying to distinguish his Afghan policy from that of President Barack Obama.

Romney tells ABC News in a Sunday interview that he supports Obama's plan to pull U.S. troops from Afghanistan by the end of 2014. But he doesn't agree with Obama's plan to order 23,000 troops out by Sept. 30, a timeline some military experts warn could complicate next year's efforts to stabilize the war-torn country.

The former Massachusetts governor says his position could change depending on the counsel of military commanders. He says he's leaving open the possibility of keeping combat troops in Afghanistan beyond 2014 should conditions change.

Romney is in Israel as part of his first overseas trip as the presumptive Republican presidential nominee.
