Perhaps Mossad has other, slightly more important things to worry about. Maybe the existential threat to their country, people, and family, posed by armed terrorists on their territory, or next to it, is a priority?
These wealthy terrorist ‘godfathers’ are hundreds of miles away from Israel, are physically ‘softer’ than the terrorists on the ground in occupied Israel, and are not a direct, physical threat to the people of Israel. The Hamass ‘godfathers’ WILL receive the wages they’ve earned from Yahweh, unless they repent and turn to Yeshua.
How they meet Shofat Tzadik (the Righteous Judge) is not yet known. Assuming that Yeshua Mashiach (Jesus Messiah) does not soon return, it is quite likely that Mossad will helpfully assist these Hamass ‘godfathers’ in arriving soon at their meeting with Elohim. Remember, Adolf Eichmann did not meet Shofat Tzadik (the Righteous Judge) until June 1, 1962.
Now how on Earth did these nonproductive terrorist get $1B?
