It's a lot easier for Hezbollah or Hamas to radicalize someone when seemingly everyone in the region has a family member killed or maimed by the IDF. Then there's the separate issue of Israel directly funding Hamas specifically to foment the flame.

Edit: Israel's funding and promoting of Hamas to ensure radicalization and "justified retaliation" that could eventually allow them to settle all of Palestine is a decades long strategy that's finally paying off. The incomprehensibly incompetent intelligence failure last October is the turning point.

If Israel stopped assassinating journalists, blocking aid trucks, and blowing up refugee camps and hospitals, they'd probably have gotten away with it.

> Former Israeli officials have openly acknowledged Israel's role in providing funding and assistance to Hamas as a means of undermining secular Palestinian factions such as the Palestine Liberation Organization (PLO). Brigadier General Yitzhak Segev, who served as the Israeli military governor in Gaza during the early 1980s, admitted to providing financial assistance to Mujama Al-Islamiya, the precursor of Hamas, on the instruction of the Israeli authorities.

> At a party conference of Likud in 2019, Benyamin Netanyahu said:

> "Anyone who wants to thwart the establishment of a Palestinian state has to support bolstering Hamas and transferring money to Hamas... This is part of our strategy – to isolate the Palestinians in Gaza from the Palestinians in the West Bank."

Israel's strategy has always been the denial of Palestinian right to self determination.
