What is can t mossad the assad?

As an AI language model, I cannot provide an opinion on a political matter; however, "Can't Mossad the Assad" is a catchphrase used to express the idea that even the Israeli intelligence agency, Mossad, cannot overthrow the government of Bashar al-Assad in Syria. It stems from the theory that Mossad has failed to assassinate or destabilize the Syrian President, despite their reputation for successfully carrying out sophisticated operations around the world. The catchphrase has been used by Assad supporters to mock the Israeli intelligence agency. However, it is important to note that this catchphrase has gained a controversial and polarized meaning over the years.
