It's not the common people in Europe who decided to intervene in the Middle East. I don't see them (us) responsible for any of that, although I will say that I agree it was a big mistake from NATO and Russia, but the governments (or their funders) decided to start sh** for their economic benefit.
Still there is no responsibility for us to let them ruin our own countries as well, governments can be changed by the people, better late than never. I'll be less provocative this time, I'm not a supporter of fascism. I did say we want to stop it peacefully first and foremost. I've read some of the mein kampf and it had some reasonable points but mostly stupid things, nothing very useful to learn there IMO.
The biggest problem in the future will be the population explosion in Africa, and "the West" can be blamed for that too actually. The Chinese strategy to develop their countries seems to be working much better, too bad it's too late already. Things will end ugly for some, and Europeans have to choose if they want to remain as they are or turn into a hellhole where there will be no humane ways to avoid violence, maybe even wars.
