1)Germany bombed Britain also using fire bombs , then later on using v1& v2 which were actually called terror weapons.
They were called "Terror Weapons" because while they were very advanced and scary, they weren't actually as effective as you think. In particular they had accuracy problems, they could only hit a target if it was literally the size of a large city, and even then they missed a few times. Luckily for Germany, that's exactly what they aimed at, with the exception of a few blowing up a small part of the English countryside.
3)Hitler decided to continue with the war but why didn't one of those spineless army officers who are always talking about honour put a bullet in his head, but here's the catch most german generals blame hitler for losing the war and that they could do better if in command so the cycle would continue probably even more death and destruction and if the war had dragged on longer then 1945 therisk of atomics being used.
There were several attempts to overthrow or kill Hitler during WW2. Many of these attempts were General Officers and members of German High Command. Everything from arresting him to suicide bombings were planned, but Hitler was a fucking accidental Houdini and somehow managed to escape alive every. single. time... Many of these he didn't even know he evaded, they simply failed because he was scheduled to show up at Place A (where he would be assassinated), only to reschedule, cancel, or go to Place B instead.
