The GOP by maintaining a death-embrace of neoliberalism and globalism, both largely nonsensical pie in the sky philosophies, have effectively ruled out any possibility of a national revitalization under its leadership. Note that the democrats are also guilty of this to a lesser extent, and on the issue of national defense the GOP is actually the slightly better of the two parties most of the time. However due to the republicans pro-elite policies they take a major hit in my rating of them.
In reality only the reorganization of American society around a meritocratic elite, a civil-military education system and the training of successive cohorts of American men and women to regard advancement in service of the state and that the nation would have their back, would solve our problems. This would be a society where whole generations of young men and young women would learn from grade-school age to work together and to value being part of a society of friends and countrymen where they learn apart from traditional education, military, technical and emergency survival and civil defense skills. Only when the populace has embraced the virtues of being part of an "organic national community" would we be able to fix our country's problems with astonishing swiftness.
Oh, great, someone making the Tea Party sounding sane!
