In my personal view, I think you can never be sure. Many countries have risen and fallen in the fray of power, and in turn, many governments change.
I consider myself a patriotic citizen of the States, the latter of which has become one of the strongest countries in the world in a surprisingly short time. But the thing is, America is still a very young country, not even half a century old. Anything can happen in the future, and it's up to the citizens in our democracy to fix it.
But I'm hoping as the years progress, history won't repeat itself, and the world becomes knowledgeable in general, where we wouldn't even require radical changes because we'd never be in the bad situation in the first place.
We've gone through some pretty tough times, longevity considered, so I'm "Hoping" that the citizens wouldn't Need to step in. But if such a time ever came, I would find it just for the system our country was founded on to do the job.
"We spend most of our time and energy in a kind of horizontal thinking. We move along the surface of things [but] there are times when we stop. We sit still. We lose ourselves in a pile of leaves or its memory. We listen and breezes from a whole other world begin to whisper." ~James Carroll
