I don't see how you can say we're crying about terrorists when obviously we're killing them all the time. In fact, the real problem is we're killing too many people around them. We take over other countries at will, level them, build them back up and then level them again. The only problem we have is we don't know how to quit and go home. You've got to learn to understand the difference between people who are saying things and making noise for a reason -- to get a vote or a donation -- and reality.
I've lived in and visited a lot of places in the world, and we're as safe and free as any major country. You give up some freedom to get orderliness and predictability so you can call the police when somebody tries to make a might vs right argument with you, and trust that your doctor has been to a school that teaches doctoring, etc. They might be freer in some parts of Somalia or something, but they pay a high price for that freedom. Despite all the BS on the internet things haven't changed for people on the ground unless you're an immigrant or you share a few habits that criminals are known to have.
I won't get into whether the government neutered the second amendment, because even if you're right there, your next statement is wrong. The U.S. has, for a lot of various and obvious historical reasons, decided that it had to outpace the rest of the world with military technology. It spends billions on R&D every year and tens of billions on acquiring equipment. The result is weaponry that civilians couldn't hope to own even if it were legal to do so, and equipment that demands highly trained crews and highly trained repair and other support personnel to operate successfully even once in a while, much less keep running and keep current -- which adds up to tens or hundreds of billions more. In other words, in order to keep ahead of -- name your adversary of choice -- the U.S. built a military that no civilian or group of civilians could keep up with no matter what happened with the second amendment. And if you look at the history of how technological advancement is connected to war and military spending, you might come to the conclusion that it was inevitable that it would eventually turn out that way.
And if it hadn't happened that way the most likely result is that we'd be a second- or third-rate power getting pushed around by the Soviet Union or China or whoever, and our lives would be a lot worse and you'd be bitching about how our politicians didn't keep us ahead of our adversaries so we could stay safe and free and so on.
Backed up the system lately?
