NBC's Tehran Bureau Chief Ali Arouzi notes that the strike that killed top Iran military commander Qassem Soleimani also killed the deputy head of Hezbollah in Lebanon, and the leader of a militia that attacked the U.S. embassy in Iraq. Arouzi says the implications of that could reach into other parts of the Middle East and draw different factions together.
