Putin said "I own all your bases"
Putin succeeded in becoming the one who decides who is the winner between Israel and Iran.
Putin could decide to close an eye letting IAF destroy those plants, and Iran won't be able to do anything about it, thus making clear his negotiational weight.
By the way Donald could learn from his master what is real bargaining in the real world, were there are no bank bailouting serial failures like him.
Or Putin could decide to dwarf Israel's strike knowing that he would speed the start of the next war, unleashing a wave of religious fanaticism that he won't be able to control.
Probably Putin hasn't any "grand plan", instead he pushes into any cracks he sees, taking advantage of any opportunity or weakness he finds around, in order to take hold of the chessboard.
It's not about Hariri, Nazrallah or Khamenei or Bibi or Donald.
It's about Putin.
