Mahmoud al-Mabhouh was the link in the dealings between Hamas acquaring arsenal from Iran, including potential nuke. This made him the MOST important person to take out for Israel. He was the link between Hamas in Gaza & Iran's Revolutionary Guard & clerical regime. The hit had nothing to do with his previous terrorist activities. It had to do with the current dealings. Israel was seeking to trump those dealings. And they succeeded. At least for now. All dealings done through him with Iran will be lost forever, & they will have to start from scratch. That is a victory for Israel. Even with the cost of the neutralization of 26+ agents with identities blown by passport photos, the risk was taken. Mossad just didn't expect Dubai police would be able to crossreference & link all the people involved in it, although the link of them to Mossad remains broken. It led to the unprecedented exposure of agents. The opperation dissintegrated into a mess, but the mission was accomplished.
