I don't even think that would do it.
Personally, I think nothing short of waiting until they are powerful enough or aligned with someone powerful enough to duke it out for the full on survival of Western Civilization will do it.
And then it will be their way of life or ours. And unless we stop this politically correct nonsense, clean up our judiciary system and do somethink about the traitors that roam our institutions and streets the outcome is less than certain.
You could well be right. It's easy to sit back and talk about how we'd do this if they did that, but the reality is that we no longer have leaders in place who understand the nature of war. They don't understand the notion of conquering an enemy.
