No it isn't. It is dressed up as being concerned about new leadership. In reality there has been next to no criticism of the regime, historically and up until this point, with some even trying to make arguments (or inferring) that it is a bad thing they have been removed. There is little concern about new leadership coming in to other countries, and there are infinite posts about the orange man every day. It is very transparent.
I haven't seen a single post say it is a bad thing to remove Khamenei. What people are saying is that there needs to be a plan in place for it to be a success. And right now there isn't one.
Your desire to defend Trump is also very transparent.
