Apparently, we learned all the wrong lessons from the Vietnam War. We were never able to seal the border and eliminate the trail so we were never able to halt reinforcement of the enemy. In addition, we at first, "looked the other way" while the SVN corrupt military and leadership got filthy rich off the opium/heroin trade and after a while actively encouraged and supported that trade to keep our "allies" on our side.
What are we doing differently in Afghanistan? Shipping a much, much, higher percentage of the heroin to the US is the only significant difference I can see. Is that how to win in Afghanistan, by making heroin so cheap and plentiful people buy it instead of their prescriptions? The US left the Golden Triangle which was the cancer that kept us from winning in Vietnam and went to the Golden Crescent to, without blinking an eye, make all the same mistakes about ourselves and our enemy again.
Come on, it's not a matter of the "adults" taking over, it's a matter of the "adults" having organized the jihad against the Soviets. In doing so, we showed the Muzlame world how to recreate what defeated us in Vietnam so they can fight the US to a standstill for as long as we're stupid enough to show up and take casualties.

After hearing Trump’s speech, as I said, the adults are now in charge.
