First Off :
War on a large scale.?—Matthew 24:7; Revelation 6:4.
Which war is he referring to that is ongoing at this present time? None that I hear of! Do you?
So the first so called prophecy is just not being fulfilled! I do not want to go into the others unless he comes with proof for the first!
Ask him not to just quote scriptures but give evidence through sources in news, or online mags or something.
