Israel are losing the war against Hamas. Prove me wrong.
You are basing your claim on the fact there is not much footage of the IDF killing Hamas militants.
The IDF are a professional military. Name me one professional military that films its combat fatalities in large quantities and then uploads it social media? The US does not even release the Bin Laden raid body cam footage.
Hamas on the other hand relish such footage for propaganda. Hence you see it.
I have seen some footage of the IDF shooting dead Hamas militants but they were filmed by civilians recording whatever transpired while out of the line of fire.
