Al Maqdeh is not Hezbollah or Hamas. He is the head of the Al Aqsa Martyrs Brigades in Lebanon.
They are part of Mahmoud abbas' Fatah party.
Munir al-Maqdeh has been smuggling weapons from Iran to terrorists in the West Bank. His brother was assassinated by Israel earlier this year. Munir has cooperated with both Hamas and Hezbollah.
Fatah in Gaza has also been active. Its Telegram channel is filled with attacks it claims on Israeli soldiers, curiously always using a 107mm mortar.
Abbas pretends to the West that he is a man of peace and against terror, while his own Al Aqsa Brigades are his terror wing.
Of course, after Hassan Nasrallah was assassinated, Mahmoud Abbas sent condolences to Hezbollah.
In every case where Abbas had to choose between Israel and the most despicable, raping, murderous terrorists, Abbas chooses the terrorists.
And the West pins all their hopes for peace on him.
