There are 2 or 3 wars which the USA has lost. These are the war in Vietnam, the war in Afghanistan and perhaps one might include the war in Iraq under George W Bush.
What is interesting is that the Vietnam war was lost in part because we were seemingly on the wrong side religiously of the conflict. At one point we were supporting a guy who was suppressing religious freedom and the North Vietnamese had believers who were a part of their leadership.
Ho Chi Min in fact attended religious services on one or more occasions.
In Afghanistan we have been supporting a state which has a state religion of Islam and we did the same thing in Iraq under Bush and Obama.
It seems that the USA should abstain from nation building nations which do not adopt or will not willingly adopt the 1st amendment!
