Based not on that foul bible but on history and common sense, I expect us to be dragged into this war the way we were into the other world wars. We will see the draft, where the maximum age will be raised to 50--and everyone drafted will be required to take coronavirus shots (for a disease that is already gone by). We will have famine, a serious energy crisis that will make 1974 look like the Year of Plenty, and major hardships. Eventually, communism will win worldwide with zero serious resistance. RFID chips become mandatory, and we will all be just like the greys.
I do not, however, expect the whole world to be destroyed by nuclear war. That is, for the reptilians, the last resort (before blowing up the whole planet) if the leaders do not capitulate to communism, which they already are. Anyone not wanting communism will be sent to the gulags, and forcibly enslaved as they were in Russia under Stalin. As such, I doubt they would want to blow up the world or use full nuclear war to destroy what they are trying to harvest.
As with the coronavirus scare, I am not as worried about the direct effects of the war itself (unless you are near the Ukraine or get drafted) as I am about the hardships, and worse the communism, that will follow.
