Hagel has gone Neo-Con?
When does he resign in disgust?
No, he hasn't gone NeoCon, he is still a realist. Keep in mind that most or many of the Realists support intervening in Syria. They were opposed in 2011 and 2012 but gradually shifted. Obama hid behind the Realists' opposition but when they shifted, Obama had to shift also.
This article is about Senate Foreign Relation Committee in regard to bombing or sending missiles into Syria but back on May 22, 2013, the committee took a vote on whether or not to arm the Syrian Rebels. That vote came out 15 votes yes and 3 votes no. So based on that we can say 15 republicans and democrats said yes. Or, 15 NeoCons, Realists, and Liberal Interventionists said yes to arming the rebels.
And there were 3 republicans and democrats who voted no to arming the rebels. Or, two antiwar democrats(Wyden and Udall) plus the one republican isolationist(Rand Paul) voted no on arming the rebels. Not long after that republican Isolationist Mike Lee joined Paul, Wyden, and Udall in introducing legislation into the Senate opposing intervening in Syria.
After that committee vote was taken there was a lot of turmoil in Congress among many members of Congress over the issue of arming the rebels and it was never voted on in the Senate. Now the question is about lobbing a few missiles in.
Senate Moves Toward Arming the Syrian Rebels
Notice in the article it says that Corker had long opposed intervening in Syria but has now shifted. Corker, who replaced Lugar as GOP chairman of the committee, is the top Realist in the Senate.
