To totally dismiss God's chastisement(tough love)upon individuals,communities and nations is unscriptural and self-righteous in itself. If He is really displeased with someone, a country or the world He can react sometimes quite forcefully to get His point across and get men to repent and seek Him. The very Bible you admonish others to read says in many places (here is a few examples) and this is all New Testament:
Romans 1:18 - For the wrath of God is revealed from heaven against all ungodliness and wickedness of men who by their wickedness suppress the truth.
Romans 2:9 - There will be tribulation and distress for every human being who does evil, the Jew first and also the Greek.
Hebrews 12:1-20
1 Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with perseverance the race that is set before us, 2 looking to Jesus the pioneer and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God. 3 Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted. 4 In your struggle against sin you have not yet resisted to the point of shedding your blood. 5 And have you forgotten the exhortation which addresses you as sons? --"My son, do not regard lightly the discipline of the Lord, nor lose courage when you are punished by him. 6 For the Lord disciplines him whom he loves, and chastises every son whom he receives." 7 It is for discipline that you have to endure. God is treating you as sons; for what son is there whom his father does not discipline? 8 If you are left without discipline, in which all have participated, then you are illegitimate children and not sons. 9 Besides this, we have had earthly fathers to discipline us and we respected them. Shall we not much more be subject to the Father of spirits and live? 10 For they disciplined us for a short time at their pleasure, but he disciplines us for our good, that we may share his holiness. 11 For the moment all discipline seems painful rather than pleasant; later it yields the peaceful fruit of righteousness to those who have been trained by it. 12 Therefore lift your drooping hands and strengthen your weak knees, 13 and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. 14 Strive for peace with all men, and for the holiness without which no one will see the Lord. 15 See to it that no one fail to obtain the grace of God; that no "root of bitterness" spring up and cause trouble, and by it the many become defiled; 16 that no one be immoral or irreligious like Esau, who sold his birthright for a single meal. 17 For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears. 18 For you have not come to what may be touched, a blazing fire, and darkness, and gloom, and a tempest, 19 and the sound of a trumpet, and a voice whose words made the hearers entreat that no further messages be spoken to them. 20 For they could not endure the order that was given, "If even a beast touches the mountain, it shall be stoned."
No. God promised Noah he would never destroy by flood again. He keeps His promises. Sorry.
