hopefully we, as Americans, can reflect enough to see the downward spiral we're in and do everything in our power to pull out of it.
Our hour in the sun has passed. The US will never dominate the world as it did through most of the 20th century.
We need to find our new proper place in the new modern world.
After emerging triumphantly unscathed from WW2, we enjoyed a couple of decades of transcendent glory, climaxing with "the Space Race" (accompanied, unfortunately, by its evil twin, the Vietnam War). This period, with extremely heavy investment in education and research, catapulted us to even greater heights of world leadership.
It has eroded steadily ever since. Reagan's disastrous economic policies accelerated it, and Bush Jr's wars clinched it. Unlike Vietnam, (which Cheney, Wolfowitz, Bush Jr, Rumsfeld, etc, had all dodged) which was an engine that was helping to drive the US economy, the current Middle Eastern wars are a gargantuan drain that have proven to be a devastating blow to our economy with no positive effects whatsoever.
Our greatest opportunity is to return to massive investments in education and research, ensuring our position as an intellectual leader in the world to come, a place that we have managed to barely and tenuously maintain in spite of everything else. With less than 5% of the world's population and approximately a quarter of its wealth, we are a large and important player, but not the only one any more.
Trump has blown a lot of hot air, but I have never heard any valid meaningful proposals for advancement come out of his mouth.
