Syria Intervention Plans Changing Rapidly

One source told Fox News military officials have changed their plans 50 times since limited action against Syria was first considered

President Obama is using the final day of the G-20 summit to build support for a U.S. military strike in Syria, even as the details of that plan continue to change by the day -- with one source telling Fox News that military officials have been asked to revise their plans 50 times since the Pentagon first began considering a "limited" action.

Obama, who arrived in Russia on Thursday to find the already failing relations with his host Vladimir Putin in even worse condition, ran into opposition from China and the European Union over a potential U.S. strike on Syria -- one of Russia's closest Mideast allies.
