That being said, I pray that America would never get into a war with either China or Russia ever again. After all, the greatest enemy of America is not China (and definitely not Russia); it is with the followers of a certain notorious 7th century warlord.
Moreover, there are plenty of evangelical Christians in China, and any major war with China would result in Christians killing Christians in a massive scale. Not exactly something that I want to see.
That indeed is sobering, and happened somewhat in WW2 in Europe and killing many UK believers in particular. Wars sometimes become necessary, but why they do is because of the lust and malice of men, which is fought against by a nation with higher principles.
But as the USA increasingly mocks God, including marrying sodomites even in the military, while persecuting Christians, judgment will come as God lifts His hand of protection, and many will wonder why. Jer. 18. Be prepared to tell them and point them to the Savior.
