Terrorism has been in China; the press is now there. Our Chinese friends tell us that Muslim extremists have been a problem for decades there, only it doesn’t get reported. But compared with what we find here and elsewhere in the world, we would probably consider it minimal.
When will the world figure out how to deal with the extremist and not let them enter their countries????? Send em back from whence they came and they can behave as they can get by with in the ME, etc.
