I'd say what failed was the neocon's policy of open borders.
Now this is a great concern. Indeed, if we are to win this war, we must also tighten our borders. Borders, language, culture.
Agree.
Everything else seems distant, and pales, while watching our very own country being literally over run by millions entering illegally, making our very own citizenship close to being pointless. With some estimates now ranging up to 25 million in our country illegally. The lawlessness here at home is epic, and the lack of government action is far beyond disturbing.
