I’d go with the definition found on Wikipedia : Neoconservatives frequently advocate the “assertive” promotion of democracy and promotion of “American national interest” in international affairs including by means of military force.
Now if that isn’t your view point , I do apologize .
I read plenty of conservative writers but none of which I’d call philosophers , besides Ayn Rand and I’m not a huge fan really.
Do you support the promotion of another countries interest?
If you don't support the promotion of democracy, do you support the promotion of anything?
All real modern conservatives, I think, begin with recognition of Edmund Burke, and in particular his book REFLECTIONS ON THE REVOLUTION IN FRANCE.
Other leading conservatives, in my opinion, include but are certainly not limited to: Friedrich von Hayek, Whitaker Chambers, G.K. Chesterton, Hilaire Belloc, James Burnham, William F. Buckley, Thomas Sowell, Joseph Sobran, Milton Friedman, Winston Churchill, and, dare I say it, Ronald Reagan.
