Something tells me we might see them coming from thousands of miles away.
No one is invading the North American Continent any time soon. The Chinese couldn’t successfully invade Taiwan.
OK, so maybe not Chinese invasion. We will die from our own internal rot and corruption first. But, once we reach some horrendous depths of depravity, corruption, and totalitarianism, just how will we die? Do we become the USSA and have to wait 50 to 100 years to throw off the yoke like the old USSR did? That sure seems to be the path we are on.
