Foreign Policy Commonalities between L.B.Johnson and neoconservatives?

Today in A.P. government class we discussed traditional post WWI foreign policy.  I present this policy as promotion of democratic capitalism through international organizations, treaties, trade agreements, humanitarian assistance programs and a strong preference for the use of military force authorized by global organizations, or at a minimum with allies while not denouncing the right of unilateral action.

We also discussed neoconservative policy.  I presented that as the promotion of democratic capitalism through the most expediate means available as determined by the United States with or without the support of international organizations and with or without allies.  I mentioned that some neoconservative leaders are former John F. Kennedy supporters who become disillusioned and inpatient with the slow pace of (classical) liberal reform through traditional means and their absolute certainty in the righteousness of their beliefs.

Here's my question to ponder.  One of my students asked if I thought Lyndon Johnson was a neoconservative.  I began reflecting on the JFK Vietnam debate, would he, or wouldn't he...  Johnson did, despite of the lack of international or allied support for our Vietnam involvement.  

Did LBJ's dramatic escalation of the country's involvment in Vietnam represent an early demonstration of neocon thought and the result?
