My impression is: all such groups are suspected and there must be some states that either invented such groups or at least support them; for it is not logical that all the world fight them and they persist in such way.
Who has the advantage: none else than Tel Aviv and their allies?
Such criminal acts like explosions in public places: such crimes cannot be justified by the Quran and the Islam religion; in fact no such alleged suicides had been cited in all the history of the Islam.
Moreover, extending the explosions to remote Muslim countries like Pakistan and Indonesia ... in order to silence those Muslim countries from protesting against the Zionist transgression on the Aqsa Mosque in Jerusalem.
This is my impression, and God is the All-Knowing.
