To what degree was the US justified in the use of total war tactics during WWII? (Address carpet/fire bombing as well as the atomic bomb)

None, because the war was started by the Jews who infiltrated the governments of the allies, especially Churchill. Had those filthy kikes not sought to destroy Germany and genocide their people as they did to the Ukrainians in the communist takeover and genocide known as the Holodomor, then Japan would've had no reason to ally with Germany. One can note that Talmudic Jews sought to destroy the Ukrainians, Russians, and Germans due to the fact that they are the true Israelites and Judeans, and now that they've accomplished that goal, the rest of the European nations are suffering the same fate. One must not worry, as they will have their portion in the lake of fire after Christ's return.
