As NATO wrapped up its 2016 Warsaw Summit, the organization agreed to continue funding Afghan security forces through the year 2020. Of course, with all that funding comes US and NATO troops, and thousands of contractors, trainers, and more.

President Obama said last week that the US must keep 3,000 more troops than planned in Afghanistan. The real reason is obvious: the mission has failed and Washington cannot bear to admit it. But Obama didn't put it that way. He said:

"It is in our national security interest, especially after all the blood and treasure we've invested over the years, that we give our partners in Afghanistan the best chance to succeed."
