Translate the following English sentence to French:
"The most serious thing, and I will end here, as there is undoubtedly far too much to be said here, is that for once, a Southern country was managing to develop, and the Northern countries, lined up behind Washington, have been unremitting in destroying it."
Le plus grave, et ce sera ma conclusion, car il y aurait décidément bien trop de choses à dire, est que, pour une fois, un pays du Sud parvenait à se développer, et que les pays du Nord, en rang derrière Washington, n'ont eu de cesse de le détruire.
