Whyhideit,
When I first read your post I thought it was too apocalyptic, definitely JW mentality at its best. But, then, you know, stuff like this is really plausible! So, what would I do?!
So help me God, if something like this or worse ever happens I hope to have the courage to do as I've planned: I shall lower my head in sign of respect for higher powers and recite the Lord's prayer (in Spanish) just as he taught us and it's registered in the Bible. Then wait 'til the chips fall where they may.
Take care!
