Very true. However, G-d does judge nations collectively. When the nation of Israel turned to rampant idolatry, they were exiled and the temple destroyed. When they turned to hatred of their fellow Jews and corrupt, the second temple was destroyed and the people exiled again.
And G-d has and will again punish the nations. He will punish the nations who have unjustly turned on His people and Nation Israel.
And that, imho, is where we are at today. We are not only a sinful depraved nation but one who collectively (54% Catholics and 45% Protestants) voted in an evil Jew hating Israel hating muslim loving president. Obama is laying the ground work for Israels destruction...And WE will pay for that as a Nation. Big time.
If God thinks Israel is right, Obama won’t be able to destroy it.
