We invaded but failed to conquer and then defence was robust and we bogged down in attrition so now we're still posturing but bleeding as we continue massacring anyway we can ot last forever so we will be defeated and have to surrender. Do it.
We polluted and depleted and destroyed and now much is desolate but we cannot admit to developing alternatives they are so do difficult and take so long and cost so much but soon world opinions will shift irrevocably to clean and green and so having left ourselves behind we would have to do so much economic catch up whilst admitting we stepped wrongly. Do it.
Once you always did it that way. For one generation perhaps more. But it's not forever. The momentum of that superstition that would not change. Prejudices, discrimination, clichés fade in significance, become meaningless, get replaced by new relevances and current significances, as you must now modify, to continue existing. Do it.
