Aging and entitlements will force the president, whether Democratic or Republican, to look for a mix of spending cuts and tax increases. The spending cuts will diminish the range of the military, and the tax hikes will ensure that economic growth doesn’t pick up. The integrity of Medicare and Social Security will be (mostly) protected, but the U.S. will lose the ability to project power around the globe.
Over a period of less than five years, China will retake Taiwan and also bring much of East and Southeast Asia into a much tighter sphere of influence. Turkey and Saudi Arabia will build nuclear weapons and become dominant players in their regions. Russia will continue to nibble at the borders of neighboring states, including Latvia and Estonia, and NATO will lose its credibility, except for a few bilateral relationships, such as with the U.K. Parts of Eastern Europe will return to fascism. NAFTA will exist on paper, but it will be under perpetual renegotiation and hemispheric relations will fray.
One area of major technological advance will be drugs, and I don’t mean beneficial pharmaceuticals. The opioid crisis eventually will subside, but new waves of ever more powerful addictive substances will arise. Easy home lab production will make interdiction at the border fruitless. More than 80,000 Americans already die from alcohol every year, and more than 60,000 from drug overdoses. Total losses from addiction will rise.
