Most Christians denominations have come out against this war, even in the USA, as I've heard.

Some people change their way of seeing the world drastically over the years, and end up fighting against the things they once fought for. But I think, more generally it's that, once you've found your way of seeing the world, you stick with that - but as the world changes around you, naturally that can mean that your relative position changes.

If you're lucky, the struggles you get into while you are young can succeed in getting the changes you believe in, or stopping the changes you don't believe in. And then you spend your energy trying to protect them against more of what seem the wrong changes.

Myself, I've still to see a lot of the changes I'd love to see, and a lot of the changes I always hated have kept happening. I think I'm a bit better at understanding how it is some people see things so different from me, but, other than that, I still have pretty well the same picture of how I'd like things to be as I did back when I was, say, 25. As the song has it:

Oh, my friend, we're older but no wiser
For in our hearts the dreams are still the same
