Or perhaps the rest of us are more realistic than you. We know there are bad guys out there who don't like the US and would like nothing better than to see it lose its power, or for some of them cease to exist. Perhaps you see this as paranoia; the rest of us see it as realism.
We're quite well aware of this. So what? They're on the other side of an ocean! They have never designed an aircraft! No one, in their entire culture, has ever designed an aircraft! In Afghanistan, a significant fraction of these people have barely Iron Age tools, left to their own devices. The only thing that makes them dangerous is other people's money and other people's weapons, and even with those things they are not especially dangerous here.
Your "realism" has made you stupid. You are willing to throw away all of the prerequisites on which this country was built. This country has done great things, but it was not a given that this would happen. It was designed. When we speak of our Founding Fathers in hushed tones and with those capital letters, it's because we are acknowledging that they were political geniuses. They designed a system that was unheard of. They took a giant step, that had never been taken before. Sure, there was precedent in things like the Magna Carta, but the Magna Carta was signed by a king. In their system, there was no slot labeled "anointed of God, his Majesty the King." That was revolutionary. But they didn't stop there. They had long arguments and wrote many papers about how a government should be designed, rather than just grow into place the way all governments before had done. And they laid out principles by which a government should run. Spying on everybody all the time is not in the rule book. It is, in fact, forbidden by the rule book they wrote. For very good reasons. The fact that you think this somehow protects you from literal Iron Age savages is mindboggling.
"America" is not a few buildings on the east coast. It is an idea. Let them try to attack us. We will still be here. Well, I will. You will be hiding under a rock somewhere, apparently. If you are willing to bow down before people claiming they have to watch everything you ever do in your entire life, cradle to grave, you have LOST. The idea is dead, and America is over. Something will go on in its place, but it won't be America.
