Afterlife

I am confused as to what exactly G-d promised after the flood-- Did G-d promise never to destroy the Earth at all? Or only with water? Because we are awfully close to WW3 (i.e. "nuclear" "war" with Russia and China). and as we all know Russia is Iran's main sponsor. so many (both Jews and Gentiles alike) are predicting that the end will occur as a result of defending Israel against Iran. Personally i am for eliminating the Iranian threat --permanently -- but i am afraid of Russia's response (which --given it's interest in securing the world's oil supplies for China--i would expect to be nuclear. (I mean --isn't there a Moshiach in the house?........anywhere? ) Nu, so tell me B'vaka-sha. Thank you and Shalom (:

Can we earn eternal life by our good works?

"And the people will oppress one another, every one his fellow and every one his neighbor; the youth will be insolent to the elder, and the despised to the honorable." (Isaiah 3:5) As I think that these verse shows the current situation of the world, because I have seen this happen frequently in many places of the earth nowadays - does Isaiah warn us about the future in this verse or did this situation start in the past and still continue?
