What Now for Republicans?

Is the GOP headed for a "civil war" within its ranks over foreign policy? How will the foreign policy of George W. Bush be assessed? Colin Dueckfires the latest salvo, in defense of conservative realism being a better fit with a "traditional Republican emphases on limited government, constitutionalism, low taxes, and limited spending at home." Perhaps not surprisingly, some of those identified with greater interventionism abroad want a larger role for government at home--so it does seem that there is a case to be made that one's views on domestic policies will influence foreign policy as well.
