Marwan Issa, deputy commander of Hamas’s army wing and the right-hand man to Deif, is believed to run lots of Hamas’s day-to-day operations, stated Daniel Byman, a senior fellow on the Heart for Strategic and Worldwide Research. With Deif spending a lot of his life incognito, Issa helps run logistical operations for the al-Qassem Brigades. Israel considers Issa a really important menace, Byman stated.
