the fact is that even if trump wins this country will be destroyed, if not the whole world,and it is assur for us to have a part in it. THere is a famous case in the gemara that if goyim come and say that “let us kill one of you or well kill all of you” it is still assur to give up that one person. SO to here, we must not do an action that contributes to destruction, even if we are saving ourselves from a worse option. The rest is not up to us.
