Will America suffer war? Some "prophets" have said the `United States will be severely persecuted and attacked by Russia, Japan, and China. Is there any biblical basis for this?

The answer is an absolute No! In no way does prophecy indicate that the United States will be severely persecuted by China or Japan.

In answer to the first question, there will be no war for America until she helps defend Israel against Russia. (Ezek. 38 and 39.) At that time, Russia will be destroyed by God with the help of the United States, one of the young lions. (Ezek. 38:13.) America, however, will neither lose a man nor suffer any destruction.
