No one is going to destroy the country; they're just going to change the culture, size and scope of government, rule of law, etc. We've handed off rulemaking to unelected bureaucrats, we've dumbed down our population, dissolved our border integrity, sold out our future generations, and handed off world power to the Chinese. All the while we've intermingled government agencies with the "private" corporations that control the distribution of information, our leaders promote policies that select winners and losers in industry, and there is constant social pressure to conform to ever changing "values" that are preached to us daily. We've formed a fascist system. Not ****, classic Italian fascist by Mussolini's own definition. If that makes you want to roll your eyes, get over it.
Don't worry, the United States isn't going anywhere, not that it means anything.
