On Sunday, the Arab League endorsed international action against the Syrian government, but did not endorse Obama's proposed plans.
The Arab League has 22 members, including Egypt, Iraq, Libya, Morocco, Jordan, Algeria, Saudi Arabia and Kuwait.
Obama's proposal has very little support around the world.
"We are alone," Manchin said. "Germany has pulled out. Great Britain had a vote against it. And an awful lot of my colleagues don't see the 'uptick' in this action."
Two terrorist groups are involved in the conflict, Manchin pointed out. Some rebels are linked to al-Qaeda, while Hezbollah supports the Assad government. Iran and Russia also support Assad.
"We don't have a friend on either side and there is no imminent threat to the U.S.," Manchin said.
"This is a democracy. I applaud the president to bring this to a vote. I am still very open-minded.
"Afghanistan is not going well. We need to get out of there. What would make me think another intervention in Syria would have a different result?"
After a White House briefing last Friday, a statement from Manchin said, "I am deeply concerned by the use of chemical weapons in Syria against innocent people.
But after over a decade of war in the Middle East, there needs to be compelling evidence that there is an imminent threat to the security of the American people or our allies before any military action is taken. I do not believe that this situation meets that threshold."Reach Paul J. Nyden at pjny...@wvgazette.com or 304-348-5164.
