I don't think there's much comparison between 2014 and 2023 given high international profile. Turkey already promised to pitch in[0] and I'd surprised if others won't follow. I'd rather put the focus on people and not buildings anyway.
I'm sorry but you don't know what you are talking about. Pledges are cheap, actually paying up the billions required to rebuild Gaza is a different matter. Yeah, we can focus on the death toll alone, but you are still wrong. 17k mostly civilians in 60 days of warfare is unprecedented in recent years.

P.S. What you wrote about Ukraine just confirms what I wrote above.
