Report Shows It's Increasingly Dangerous To Be A Christian In Many Countries

Open Doors USA released its annual list of the most dangerous countries for Christians. Among those where anti-Christian hostility has grown are India and Turkey, two important U.S. allies. ...

Among the 50 countries on this watch list are ones you'd expect. North Korea is the worst place to be a Christian. Afghanistan is a close second. Most are countries where Islamist radicals target non-Muslims.

And the biggest offender is Afghanistan, which the USA has occupied since 2002.

Will someone please explain to me why the USA fights Islamic wars, for Islamic causes, and installs Islamic governments that persecute Christians?
