Sure everyone with a different opinion is victim of propaganda. Easy way out.

There are of course similarities, like both conflicts are fueled by nationalistic ideology but alone Russian goals are quite different, one is more of a conventional war - the other is asymmetric, Palestinians had a very limited control over their territories to begin with and there is a long complex history of aggression from both sides. Most importantly there is a functioning solution for Ukrainian conflict that can be achieved with military, not so sure there is such a solution for Israel/Palestine conflict - people were searching for one, for quite some time.
