If God smites the US, it won't be just because of a lack of supporting Israel (that is only one symptom of the problem.)It will be because the US has abandoned God and morals. If we as a people hadn't become so morally degraded, then much of this situation wouldn't be happening in the first place. We have allowed evil to take over our society by our complacency and indifference to it. After a couple of generations of allowing moral degradation, being complacent to immorality in the public square, while pushing God out of the public square; the chickens have come home to roost. This situation has been a long time in the making. If people repent maybe disaster could be avoided, but do you think that many will turn to God without a chastisement? Time will tell, I guess.
The American people are about as likely to repent as the last defenders of Sodom and Gomorrah.
