Exactly. The modern liberal is more a cross between a socialist and a capitalist, with just a little bit of communist thrown in. Really there is not a whole lot of difference in the goal of Republicans and Dims. The big difference is how they plan to go about it.
As I have said before, libertarians are more like Blue Dog Democrats. They still want the personal freedoms but do not believe in a large government or strong defense.
I think libertarians believe in strong defense but minimal intervention. Both D and R believe in intervention, but on their own terms(which vary widely).
