On one of the previous ground tracks, I noticed the booster would pass directly over Israel--too bad it missed!
This was actually the second launch of the Long March 5B core stage-only variant, with the first being in May 2020. I don't recall this big of hoopla over that one which also made an uncontrolled reentry. Just convenient now due to the ramped-up China propaganda in the media, I suppose. CNSA is going to launch at least four more CZ-5Bs to complete the space station by 2022. I don't know how much of a weight penalty it would have been to add some deorbit retrorockets on the booster, the Chinese didn't consider it to be a big priority.
