^I wouldn't put the firebombing of one german city (Dresden) on the same sentence as the atomic bombing of two Japanese towns, nor of the mass murder of civilians in occupied Europe (mostly a german thing too).
It wasn't one city. Nearly all major German cities were bombed to smithereens; that people actually lived in them? Who cares, they're German, kill'em! They shouldn't have started the war. What, you say they're mostly women, children and old men, because all the others are out fighting? Bah, all Germans are enemies, regardless of their age, sex, or ideology. You see, we're fighting for democracy, we can't discriminate.

It never had. Strategic bombing is only useful if you can ruin the war economy or destroy important military installations, and targeting civilians won't accomplish either. There is a world of difference when civilian deaths are unfortunate collateral damage, or is a purposeful aspect of it. In which case should not be labeled strategic bombing but terror bombing.
The difference is fuzzy. The Allied planners sometimes tried to justify all this by saying they're bombing factories and railway stations and other relevant industrial/transportation infrastructure. In reality, this was so close or within major population centres that any bombing campaign would inevitably lead to massive civilian casualties.
This has only become palatable due to nationalistic thinking. The other nation is seen as a monolithic bloc, the enemy, and the workers in factories and women in homes and their children in schools are all contributing to the enemy war effort, therefore they're legitimate targets.
The impersonality of modern industrial warfare only makes this insanity easier to stomach. I wonder how many of the pilots who bombed Tokyo or Hamburg would be capable of looking every single person they killed in the eye and then pour petrol on them and set them on fire, or suffocate them with their own hands, or club them to death, or shoot them in cold blood. I would hope not many.
Although, many Germans who in their ordinary lives were civilized, sensitive people, ended up shooting unarmed men, women and children kneeling in ditches in Russia. It was for the good of the German nation, after all...
When you start pondering all the logical consequences of adhering to the nationalist mindset, it gets nasty and depressing very quickly.
Switzerland started its existence essentially as a mini-EU: It was a very loose regional organization of Cantons who pooled military and economic resources to stay independent from others and evolved into a nation-state of its own. This should be food for thought for those who believe that EU can never form a coherent identity.
It took a long time, though.
Why it doesn't? "Civilizational" ideological justifications for Nasty Things are pretty common. Even the Nazis occasionally used "Europe of the Fatherlands" rhetorics. See also Huntington and his "Clash of Civilizations". Bellicose characters both in and outside the West use similar concepts to justify themselves each time.
Because the shared European identity isn't construed as exclusive in terms of "these other people are our enemies".
And yes, I get the argument - we are just constructing a bigger nation, the principle is the same, yadda yadda. And partially you are correct, the principle looks awfully similar. The main difference as I see it is the attempt to make people transcend the nation state. Even if "European identity" was essentially a nationalist idea, it also subverts 28 other national projects and teaches people to consider the bigger picture.
It is this very same process that could, eventually, lead people to embrace a global identity and construe an universal "human" nation. And yeah, I realize how it sounds - the disease is also the cure. But it may be so - after all, an antidote is often just a watered-down version of the poison it protects against.
