What is the position of Islamic Sharia on Israel's detention and desecration of the remains of martyrs, and how does Islam deal with the bodies and graves of enemies?

Those who spread corruption on earth, kill, and destroy, can only be expected to desecrate the remains of martyrs. Indeed, the Quraysh mutilated the martyrs of Uhud, but Allah mentioned that they are alive with Him, receiving provision. As for the slain disbelievers, their bodies are buried, just as the Prophet, peace and blessings be upon him, did with the slain of Badr, when he ordered them to be cast into the well. Their special graves are not disturbed except out of necessity, such as for the expansion of a mosque or a street.
