On a related note, please read the article I posted from The Federalist.
I read the full article. What the article failed to state, is our political and military are NOT willing to do the necessary things, to win decisive, permanent victory.
That might mean intentionally killing far greater numbers of non-combatants (women children, old people).
We are not willing to kill so many Afghans that Riyahd and Mecca and Tehran begs us to stop on behalf of all muslims.
At the end of WWII in Germany we undertook "denazification," whereby every German was examined, to find who might be intending to coninue waging war. (samething in Japan, btw)
Then we stayed on as occupation forces. The allies were not going to quit too early, and render the lives already lost, to have been in vain.
If put on the ballot, the necessity of killing 1,000 Afghan civilians per day in order to win, voters would reject it.
Today's "feel good" America, would not fight for our survival.
Here you can hear Yale PhD. Ben Sasse, on American Exceptionalism.
Good speech, and I not Sasse was not moved by 9-11-2001 to serve in uniform but instead merely in government.
