This is part of the Guardian article by Jonathon Freedland for anyone who wants to read it! I'd read the whole article though!
"Prime minister for most of the last 15 years, Netanyahu has been an enabler of Hamas, building up the organisation, letting it rule Gaza unhindered – save for brief, periodic military operations against it – and allowing funds from its Gulf patrons to keep it flush. Netanyahu liked the idea of the Palestinians as a house divided – Fatah in the West Bank, Hamas in Gaza – because it allowed him to insist that there was no Palestinian partner he could do business with. That meant no peace process, no prospect of a Palestinian state, and no demand for Israeli territorial concessions.
None of this was a secret. In March 2019, Netanyahu told his Likud colleagues: “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.”
This is why Hamas was able to commit the atrocities they did, Netanyahu was complicit in allowing them to gain strength and confidence because it suited his purpose. This is why he is being blamed by many Israelis for the deaths and the hostage taking. Suddenly the idea that he might have ignored the warnings with regard to an attack by Hamas seems less like a conspiracy story. He doesn't want Gaza but he does want to destroy Gaza. Actually I think what he wants is to be able to continue annexing more of the West Bank.
