“They all know that Yehova is going to declare war on them, and they are just getting ready.”
I respectfully disagree. They simply don’t believe in Yehova (using your spelling — not saying it is wrong, but have seen several).
If they did believe in Him at all, they’d know that even nukes would be less than insect bites to Him or His returned Son, and their bunkers would be meaningless.
Their brains don’t work all that deeply, or they wouldn’t be liberals.
