I don't know...Wasn't regular old conservatism good enough? Also, those decribed as "neoconservatives" are often into government centralization, globalism, big spending, etc. Not good things.
As conservative, I find neoconservatism congenial. Like back during the Cold War, when we needed a muscular approach to the present danger, neoconservatism supplied the intellectual ammunition that brought us to victory. Now its supplying the intellectual framework to sustain through our decades long battle with Islamofascism. Its a good thing the Brits are catching on - finally!
