The question was asked before the final confirmation that the Iranian president Raisi was dead, but was asked while he was presumed dead but the search was ongoing. The question posed was with the news that one of the greatest enemies who made a lot of trouble for the Jews has seemingly died. When we will find out that he definitely has died should one maker the bracha of Hatov VeHameitiv? On the one hgand it will be joyous news, on the other hand another enemy and hater of the Jews will be appointed in his place so maybe there is no place  to make a bracha?

Rav Zilbershtein paskened that one should buy a new fruit and say a conditional bracha saying that if I can make the shehecheyanu on the news, I am making the bracha on both the fruit and on the news of Raisi's death, but if not then the bracha is only on the watermelon but not on the death of the wicked one.
